0.4(g-9)=0.9(g-4)

Solution for 0.4(g-9)=0.9(g-4) equation:

Simplifying
0.4(g + -9) = 0.9(g + -4)

Reorder the terms:
0.4(-9 + g) = 0.9(g + -4)
(-9 * 0.4 + g * 0.4) = 0.9(g + -4)
(-3.6 + 0.4g) = 0.9(g + -4)

Reorder the terms:
-3.6 + 0.4g = 0.9(-4 + g)
-3.6 + 0.4g = (-4 * 0.9 + g * 0.9)
-3.6 + 0.4g = (-3.6 + 0.9g)

Add '3.6' to each side of the equation.
-3.6 + 3.6 + 0.4g = -3.6 + 3.6 + 0.9g

Combine like terms: -3.6 + 3.6 = 0.0
0.0 + 0.4g = -3.6 + 3.6 + 0.9g
0.4g = -3.6 + 3.6 + 0.9g

Combine like terms: -3.6 + 3.6 = 0.0
0.4g = 0.0 + 0.9g
0.4g = 0.9g

Solving
0.4g = 0.9g

Solving for variable 'g'.

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

Add '-0.9g' to each side of the equation.
0.4g + -0.9g = 0.9g + -0.9g

Combine like terms: 0.4g + -0.9g = -0.5g
-0.5g = 0.9g + -0.9g

Combine like terms: 0.9g + -0.9g = 0.0
-0.5g = 0.0

Divide each side by '-0.5'.
g = 0

Simplifying
g = 0
