Question:Omg im so sick of asking for help. (9t)(t+6)=t
Ok so i got the answer T=1 but my friend said it was wrong and he taught me but he taught it in a confusing way. I subtracted 6 from 9 and got 3. then i subtracted tt and got 2t. I took the t from the right side and subtracted that and got 3x and then 3/3 is equal to 1.
what am i doing wrong. im so confused. like how do you know when your suppose to subtract a variable? which variable to do first left or right? I need help on this because im so confused in solving equations with two variables. Anyone have a site that teaches how to do everysingle problem in the book?
Answers:first you want to simplify the left side of the equation starting with (9t)(t+6)=t we first need to get rid of the grouping symbols () so we get 9tt6 = t it sounds to me like you got to their fine. Next we want to combine like terms. 9 and 6 and the ts on the left side to get 3  2t = t now we can add the 2t to the right side of the equation and get 3 = 3t divide both sides by 3 and get t = 1 Hope that helps.

Question:I am having the hardest time with this. I don't get it all. I've looked at a bunch of sites, but all their examples have equations that look like 347x=6+2x and mine doesn't look like that! Nothing is attached to my variable. One of my problems is 7*x8=x7*5. Can someone please give me a step by step on how to solve equations like this? Merci beaucoup! the stars are for multiplication.
Answers:What do the stars represent? Multiplication? Is this the equation you're asking about: 7x  8 = x  35

Question:Could you help me by telling me how the following examples are done? Thank you.
1: 2(c6)=9c+2
2: 9+5n=5n1
Answers:Let's do the first one. Start by getting rid of the parentheses: 2c  12 = 9c + 2 Now move the cterms to the left side and the unit terms to the right: 2c  9c = 2 + 12 Combine like terms: 7c = 14 Then divide by the coefficient of the variable: c = 14/(7) c = 2 There's your answer! The second one is a little tricky. First, move the variables to the left side and units to the right: 5n  5n = 1 9 0 = 10 Since there's no value of n that makes zero equal to 10, this tells you that there's no value of n that solves the equation. In other words, the equation has no solution. Hope that helps!

Question:1. j=204j
2. 8/9x=8+4/9x
Answers:1.))) j=204j 4j 4j subtract 4j from each side 3j=20  divide each side by 3 3 3 3j divided by 3 (the threes cancel out) j=6.66666667 2.))) 8/9x=8+4/9x 9x is on BOTH sides, so they go away 8=8+4 8=12 2=3 your final answer will be NO NUMBERS, because you cannot finalize the bottom numbers to one
