Answer:

g = 4

Step-by-step explanation:

3.2g + 7 = 1.2g + 15 (Given)

3.2g + 7 - 7 = 1.2g + 15 - 7 (Subtraction Property of Equality)

3.2g = 1.2g + 8 (Simplify)

3.2g - 1.2g = 1.2g - 1.2g + 8 (Subtraction Property of Equality)

2g = 8 (Simplify)

[tex]\frac{2g}{2} = \frac{8}{2}[/tex] (Division Property of Equality)

g = 4 (Simplify)

Step-by-step explanation:

Subtract 1.2 from each side then subtract 7 from both sides and divide both sides by 2
