Question

Find the value of x ?

Answer 1

(2x + 60) + (3x - 40) = 180

2x + 60 + 3x - 40 = 180

5x + 20 = 180

5x = 180 - 20

5x = 160

x =160/5 = 32

x = 32

Answer 2

Step-by-step explanation:

$2x \: + 60 + 3x - 40 = 180 \: \\ {(linear \: pair \:) } \\ 5x + 20 = 180 \\ 5x = 180 - 20 \\ 5x = 160 \\ x = 160 \div 5 = 32$
