5x - 4x = 13 - 3 ie x = 10

-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5

5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12

If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.

8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0

3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3

3x - 7 = 5x + 13-2x = 20x = -10

If: 3x-7 = 5x+13 Then: x = -10

X=10.

x=-3

88=13+5x -13 -13 75= 5x 75/5 =15 x=15

(3, -4)
