Solve for x
1) 2x + 5 = 30 - 3x
2) -4 (11x +2) = 80
3) 3x + 1 + 32 = 180
1 answer:
1) x = 5
2x + 5 = 30 - 3x
(+ 3x)
5x + 5 = 30
(- 5)
5x = 25
( / 5)
x = 5
2) x = -2
(-4 * 11x) + (-4 * 2) = 80
-44x - 8 = 80
(+ 8)
-44x = 88
( / -44)
x = -2
3) x = 49
3x + 33 = 180
(- 33)
3x = 147
( / 3)
x = 49
I hope this helps! The / symbol means divide by the way :)
