Which expression is equivalent to 11 plus 2x minus 7 plus 3x?
5x + 4
5x plus 7 equals 3x-21?
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
-3x plus 7 equals 2x-18?
-3x+7=2x-18 ---> 7+18=2x-3x ----> 25=5x ----> x=5
2x plus 12-3x equals 5?
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
What is -3x plus -18 equals 2x plus 7?
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line

How do you solve 3x plus 4 equals 2x - 3?
3x+4 = 2x-3 3x-2x = -3-4 x = -7
What is x plus 4 plus 2x-7?
It is: x+4+2x-7 = 3x-3 simplified
3x plus 2 equals 2x - 5 what is x?
3X+2=2X-5 -2 -2 __________ 3X= 2X-7 -2X -2X __________ X=-7 Check: 3(-7)+2=2(-7)-5 -19=-19 :)
What is the sum of (x-4) plus (2x-7)?
(x - 4) + (2x - 7) = 3x - 11 You get that by: Adding the x terms (one plus two) to get 3x; and adding the plain (non-x) numbers together. In this can both plain numbers are negative, so you get a negative of eleven, which is the sum of the absolute values 4 and 7.
15 plus 14 plus 14 plus 11 plus 2x plus x equals 75?
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
