5x+y=-7 3x+y=15 8=D

3x - 5 + 3x = 1x + 15 3x + 3x -1x = 15 + 5 5x = 20 5x/5 = 20/5 x = 4

x = 27

2x+3x = 5x

3x 11 5x=75 x=8

5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500

5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5

5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4

5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.

5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375

2x + 3x + 6 = 5x + 6

3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)

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

The answer is -8.

2x-12

No.

32-5x=3x+8 32-5x-8=3x+8-8 24-5x=3x 24-5x+5x=3x+5x 24=8x x=24/8=3

5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4

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

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

6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2

3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3

(1, 0)

x= 9
