.3+.2(g+7)=1.5

Solution for .3+.2(g+7)=1.5 equation:

Simplifying
0.3 + 0.2(g + 7) = 1.5

Reorder the terms:
0.3 + 0.2(7 + g) = 1.5
0.3 + (7 * 0.2 + g * 0.2) = 1.5
0.3 + (1.4 + 0.2g) = 1.5

Combine like terms: 0.3 + 1.4 = 1.7
1.7 + 0.2g = 1.5

Solving
1.7 + 0.2g = 1.5

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-1.7' to each side of the equation.
1.7 + -1.7 + 0.2g = 1.5 + -1.7

Combine like terms: 1.7 + -1.7 = 0.0
0.0 + 0.2g = 1.5 + -1.7
0.2g = 1.5 + -1.7

Combine like terms: 1.5 + -1.7 = -0.2
0.2g = -0.2

Divide each side by '0.2'.
g = -1

Simplifying
g = -1
