Question

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

Answer 1

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
