The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.

7x-5x=8 2x=8 x=4

It is: 12x

142

5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2

7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5

x=6

7x-5x=8 2x=8 x=4

(1) 5x+y=-12 (2) 7x-3y=-30 From (1) one gets y = -12-5x Put into (2) 7x-3y = 7x -3 (-12-5x) = 7x + 36 +15 x = 22x +36=-30 22x = -30-36 = -66 so x = -3 and y=-12-5x = -12-5x-3= 3 The solution is (-3,3)

It is: 12x

7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
