The value 6.5 does.
It is an equation and the value of x is 2
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
2 + 2x = 18 2x = 18 - 2 2x = 16 x = 8

How do you add 2x plus 3y equals 18 in 5x-y equals 11
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
12+2x = 6x-18 12+18 = 6x-2x 30 = 4x Divide both sides of the equation by 4 to find the value of x: x = 7.5
2x + 10 = 182x = 8x = 4
