Question

Find the value of x in this equation X+Y=5 and 2X-Y=7

Answer 1

x = 4

Explanation:

to find the value of x that satisfies both equations, solve them simultaneously.

x + y = 5 → (1)

2x - y = 7 → (2)

add (1) and (2) term vy term to eliminate y

3x + 0 = 12

3x = 12 ( divide both sides by 3 )

x = 4
