Answer:
C.) -3x + 6 = -9
Step-by-step explanation:
2x - 4 = 6 |add 4 to both sides
2x = 10 |divide both sides by 2
x = 5
a)
5x - 6 = -11 |add 6 to both sides
5x = -5 |divide both sides by 5
x = -1 ≠5
b)
-4x - 2 = 10 |add 2 to both sides
-4x = 12 |divide both sides by (-4)
x = -3 ≠5
c)
-3x + 6 = -9 |subtract 6 from both sides
-3x = -15 |divide both sides by (-3)
x = 5 √
d)
2x + 3 = 7 |subtract 3 from both sides
2x = 4 |divide both sides by 2
x = 2 ≠5
