Answer 1

Answer:

Simplifying

3x * 5x = 135

Reorder the terms for easier multiplication:

3 * 5x * x = 135

Multiply 3 * 5

15x * x = 135

Multiply x * x

15x2 = 135

Solving

15x2 = 135

Solving for variable 'x'.

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

Divide each side by '15'.

x2 = 9

Simplifying

Take the square root of each side:

x = {-3, 3}
