Solve for e. 9e-7=7e-11

Simplifying 9e + - 7 = 7e + - 11

Reorder the terms: - 7 + 9e = 7e + - 11

Reorder the terms: - 7 + 9e = - 11 + 7e

Solving - 7 + 9e = - 11 + 7e

Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right.

Add '-7e' to each side of the equation. - 7 + 9e + - 7e = - 11 + 7e + - 7e Combine like terms: 9e + - 7e = 2e - 7 + 2e = - 11 + 7e + - 7e

Combine like terms: 7e + - 7e = 0 - 7 + 2e = - 11 + 0 - 7 + 2e = - 11

Add '7' to each side of the equation.

Combine like terms: - 7 + 7 = 0 0 + 2e = - 11 + 7 2e = - 11 + 7

Combine like terms: - 11 + 7 = - 4 2e = - 4

Divide each side by '2'. e = - 2

Simplifying e = - 2
