Question

17x-7x=40.
X + x =46.
5x+6x=22.
X+2x=39.
5x+3x=24.
3x-2=52.
-9x+10=91.
2x+5=-1

Answer 1

17x - 7x = 40

10x = 40

x = 40/10

x = 4

x+x = 46

2x = 46

x = 46/2

x = 23

5x + 6x = 22

11x = 22

x = 22/11

x = 2

x + 2x = 39

3x = 39

x = 39/3

x = 13

5x + 3x = 24

8x = 24

x = 24/8

x = 3
