Question

Which could be a step used when solving the equation 5x + 10 = 7.5x

Answer 1

5x + 10 = 7.5x
-5x. -5x subtract -5x from both sides
+10 = 2.5x
——————. divide 2.5 from both sides
2.5. 2.5
4 = x
x = 4

Answer 2

x = 4

Move variables to the right and constants to the left. Then divide.

Explanation:

5x + 10 = 7.5x (Given)

-2.5x = -10 (subtraction property of equality)

x = 4 (division property of equality)
