I can't figure out this problem: AX+BY=C SOLVE FOR Y AX+BY=C SOLVE FOR Y subtract AX from both sides. AX - AX + BY = C - AX combine terms. BY = C - AX divide both sides by B BY/B = (C-AX)/B Y = (C-AX)/B

2x + 1/2 = x/2 + 1/3 Subtract the x/2 from both sides to get 2x + 1/2 - x/2 = + 1/3 Now subtract 1/2 from both sides to get 2x + - x/2 = 1/3 - 1/2 Then combine terms on both sides and solve for x. Subtract the x/2 from both sides to get 2x + 1/2 - x/2 = +

how do you write an equation and state what the variable n represnts. 54 -n- =24 If you're writing an equation where you need to state what the variable is, then you need to end up with an equation where n is the only thing on one side of the equal sign.

okay so using y = (-5/6)x + 3 how do i find the corresponding value for y when x = 12? here was the previous work to the problem. 5x+6y=18 solve for y 5x + 6y = 18 Subtract 5x from both sides. 6y = 18 - 5x Divide by 6 y = (18-5x)/6 or 3 - (5/6)x

3-3r=4 Do you wish to solve for r? Put r on one side and everything else on the other. First substract 3 from both sides. 3-3-3r = 4 - 3 combine. -3r = 1 Multiply by -1 3r = -1 Divide both sides by 3 3r/3 = -1/3 r = -1/3

If 4X + Y =H, Then X is equal to? 4X + Y =H Move Y to other side by subtracting Y from both sides. 4X + Y - Y = H - Y Combine terms. 4X = H - Y Now divide both sides by 4 to get 1X. 4X/4 = (H - Y)/4 X = (H-Y)4 or (1/4)(H-Y)
