4 is less than 12+x (Idon'y know how to make the less than sign on the computer) I've subtracted 12 form each side and I get 8. What am I doing wrong? 2m5=17 I added 5 to each side and get 22. Then divide by 2 get 11. Is that coeerct? 4 < 12 + x 16 <

I need help with this problem, (3x)/4 = (x+6)/3 Thanks! I've tried it myself several times and I keep getting stuck. multiply both sides of the equation by 12 Yields 93x=4x24 add 4x to each side, subtract 9 from each side. I don't really see how that

hi i rearranged these terms into y=mx+b can you plz check and see if they're right? 1. 2x+5y16=0 2. 4x3y6=0 3. 3x+y+2=0 1. 5y=2x+16 2.3y=4x+6 3. y= 3x2 tnx ^^ On the first two, you need to divide each side by the coefficent of y. On two, what

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 = (185x)/6 or 3  (5/6)x

33r=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. 333r = 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 = (HY)4 or (1/4)(HY)

how would you do this prob. negative4(5y+6) = negative 7y+3 thanks. happy halloween I'm going to assume your problem is this: 4  (5y + 6) = 7y + 3 If that's the case, distribute the negative over the terms in the parentheses first: 4  5y  6 = 7y +
