Question

2(x - 10) = 59
What are the steps to come to the correct answer?

Answer 1

39.5

Explanation:

Open the bracket by multiplying the numbers in the bracket by 2

2x-20=59

collect like terms(-20 crossing over the equal sign will become +20

2x=59+20

2x=79

Divide both sides by 2

`(2x)/(2) =(79)/(2)`

x=39.5
