-2(e+f)-(2e+5f)=

Solution for -2(e+f)-(2e+5f)= equation:

Simplifying
-2(e + f) + -1(2e + 5f) = 0
(e * -2 + f * -2) + -1(2e + 5f) = 0
(-2e + -2f) + -1(2e + 5f) = 0
-2e + -2f + (2e * -1 + 5f * -1) = 0
-2e + -2f + (-2e + -5f) = 0

Reorder the terms:
-2e + -2e + -2f + -5f = 0

Combine like terms: -2e + -2e = -4e
-4e + -2f + -5f = 0

Combine like terms: -2f + -5f = -7f
-4e + -7f = 0

Solving
-4e + -7f = 0

Solving for variable 'e'.

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

Add '7f' to each side of the equation.
-4e + -7f + 7f = 0 + 7f

Combine like terms: -7f + 7f = 0
-4e + 0 = 0 + 7f
-4e = 0 + 7f
Remove the zero:
-4e = 7f

Divide each side by '-4'.
e = -1.75f

Simplifying
e = -1.75f
