Question

solve - 13(X+20)=39​

Answer 1

Answer:

Simplifying

13(x + -3) = 39

Reorder the terms:

13(-3 + x) = 39

(-3 * 13 + x * 13) = 39

(-39 + 13x) = 39

Solving

-39 + 13x = 39

Solving for variable 'x'.

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

Add '39' to each side of the equation.

-39 + 39 + 13x = 39 + 39

Combine like terms: -39 + 39 = 0

0 + 13x = 39 + 39

13x = 39 + 39

Combine like terms: 39 + 39 = 78

13x = 78

Divide each side by '13'.

x = 6

Simplifying

x = 6
