Solution for ((7)(a+x))=(b)-(a)+(2x) equation:


Simplifying
((7)(a + x)) = (b) + -1(a) + (2x)
((a * 7 + x * 7)) = (b) + -1(a) + (2x)
((7a + 7x)) = (b) + -1(a) + (2x)
(7a + 7x) = (b) + -1(a) + (2x)

Remove parenthesis around (7a + 7x)
7a + 7x = (b) + -1(a) + (2x)
7a + 7x = b + -1(a) + (2x)

7a + 7x = -1a + b + (2x)

Solving
7a + 7x = -1a + b + (2x)

Solving for variable 'a'.

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

Add 'a' to each side of the equation.
7a + a + 7x = -1a + b + a + (2x)

Combine like terms: 7a + a = 8a
8a + 7x = -1a + b + a + (2x)

Reorder the terms:
8a + 7x = -1a + a + b + (2x)

Combine like terms: -1a + a = 0
8a + 7x = 0 + b + (2x)
8a + 7x = b + (2x)

Add '-7x' to each side of the equation.
8a + 7x + -7x = b + (2x) + -7x

Combine like terms: 7x + -7x = 0
8a + 0 = b + (2x) + -7x
8a = b + (2x) + -7x

Combine like terms: (2x) + -7x = -5x
8a = b + -5x

Divide each side by '8'.
a = 0.125b + -0.625x
