f(2+a)=5(2+a)-7

Solution for f(2+a)=5(2+a)-7 equation:

Simplifying
f(2 + a) = 5(2 + a) + -7
(2 * f + a * f) = 5(2 + a) + -7

Reorder the terms:
(af + 2f) = 5(2 + a) + -7
(af + 2f) = 5(2 + a) + -7
af + 2f = (2 * 5 + a * 5) + -7
af + 2f = (10 + 5a) + -7

Reorder the terms:
af + 2f = 10 + -7 + 5a

Combine like terms: 10 + -7 = 3
af + 2f = 3 + 5a

Solving
af + 2f = 3 + 5a

Solving for variable 'a'.

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

Add '-5a' to each side of the equation.
af + -5a + 2f = 3 + 5a + -5a

Reorder the terms:
-5a + af + 2f = 3 + 5a + -5a

Combine like terms: 5a + -5a = 0
-5a + af + 2f = 3 + 0
-5a + af + 2f = 3

Add '-2f' to each side of the equation.
-5a + af + 2f + -2f = 3 + -2f

Combine like terms: 2f + -2f = 0
-5a + af + 0 = 3 + -2f
-5a + af = 3 + -2f

Reorder the terms:
-3 + -5a + af + 2f = 3 + -2f + -3 + 2f

Reorder the terms:
-3 + -5a + af + 2f = 3 + -3 + -2f + 2f

Combine like terms: 3 + -3 = 0
-3 + -5a + af + 2f = 0 + -2f + 2f
-3 + -5a + af + 2f = -2f + 2f

Combine like terms: -2f + 2f = 0
-3 + -5a + af + 2f = 0
