Question

x + y = 60 ; 2x - y = 90 what is the value of x answer​

Answer 1

Answer:

value of x = 50

Step-by-step explanation:

x+y = 60......(×2)

2x-y = 90.....(×1)

2x+2y = 120.....equation 1

2x-y = 90.....equation 2

substracting equation 1 and 2

3y = 30

y = 10

putting value of y on equation 2

value of x = 50
