Question

90-x =1 /3(180-x) find x​

Answer 1

Step-by-step explanation:

90-x = 60-x/3

270- 3x = 60-x

270-60 = -x+3x

210 = 2x

x= 105

Answer 2

Answer: x = 45

Step-by-step explanation:

90 - x = 1/3(180 - x)

90 - x = 60 -1/3x

90 - x = 60 - x/3

90 - 60 = x - x/3

30 = (3x - x)/3

30 = 2x/3

30 × 3 = 2x

90 = 2x

x = 90/2

x = 45
