2.9f+g-(-1.3f-g)=

Solution for 2.9f+g-(-1.3f-g)= equation:

Simplifying
2.9f + g + -1(-1.3f + -1g) = 0
2.9f + g + (-1.3f * -1 + -1g * -1) = 0
2.9f + g + (1.3f + 1g) = 0

Reorder the terms:
2.9f + 1.3f + g + 1g = 0

Combine like terms: 2.9f + 1.3f = 4.2f
4.2f + g + 1g = 0

Combine like terms: g + 1g = 2g
4.2f + 2g = 0

Solving
4.2f + 2g = 0

Solving for variable 'f'.

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

Add '-2g' to each side of the equation.
4.2f + 2g + -2g = 0 + -2g

Combine like terms: 2g + -2g = 0
4.2f + 0 = 0 + -2g
4.2f = 0 + -2g
Remove the zero:
4.2f = -2g

Divide each side by '4.2'.
f = -0.4761904762g

Simplifying
f = -0.4761904762g
