10.2=7(1+r)8power

Solution for 10.2=7(1+r)8power equation:

Simplifying
10.2 = 7(1 + r) * 8power

Reorder the terms for easier multiplication:
10.2 = 7 * 8eoprw(1 + r)

Multiply 7 * 8
10.2 = 56eoprw(1 + r)
10.2 = (1 * 56eoprw + r * 56eoprw)
10.2 = (56eoprw + 56eopr2w)

Solving
10.2 = 56eoprw + 56eopr2w

Solving for variable 'e'.

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

Add '-56eoprw' to each side of the equation.
10.2 + -56eoprw = 56eoprw + -56eoprw + 56eopr2w

Combine like terms: 56eoprw + -56eoprw = 0
10.2 + -56eoprw = 0 + 56eopr2w
10.2 + -56eoprw = 56eopr2w

Add '-56eopr2w' to each side of the equation.
10.2 + -56eoprw + -56eopr2w = 56eopr2w + -56eopr2w

Combine like terms: 56eopr2w + -56eopr2w = 0
10.2 + -56eoprw + -56eopr2w = 0

Add '-10.2' to each side of the equation.
10.2 + -56eoprw + -10.2 + -56eopr2w = 0 + -10.2

Reorder the terms:
10.2 + -10.2 + -56eoprw + -56eopr2w = 0 + -10.2

Combine like terms: 10.2 + -10.2 = 0.0
0.0 + -56eoprw + -56eopr2w = 0 + -10.2
-56eoprw + -56eopr2w = 0 + -10.2

Combine like terms: 0 + -10.2 = -10.2
-56eoprw + -56eopr2w = -10.2

Reorder the terms:
10.2 + -56eoprw + -56eopr2w = -10.2 + 10.2

Combine like terms: -10.2 + 10.2 = 0.0
10.2 + -56eoprw + -56eopr2w = 0.0
