- 7X - 2 = 24 - 9X
add 9X to both sides
2X - 2 = 24
add 2 to both sides
2X = 26
divide both sides by 2
X = 13
---------------------check in original equation
- 7(13) - 2 = 24 - 9(13)
- 91 - 2 = 24 - 117
- 93 = - 93
checks
7x2- 63 = -35, when x equals 2
31
That equals 28
yes
7x2 plus 7x5 = 49

-20
2
7x2 + y
7x2
The solution: x = 6/7 and x = -1
