Answer:
x = 4 y = 2
Step-by-step explanation:
2x + y = 10
2x4 = 8
8 + 2 = 10
2x - y = 6
2x4 = 8
8 - 2 = 6
Answer:
Step-by-step explanation:
2x + y = 10......(1)
2x - y = 6........(2)
Substracting (2) from (1)
2x - 2x + y - (-y) = 10 - 6
y + y = 4
2y = 4
Dividing through by 2
y = 4/2
y = 2
Substitute y = 2 in (2)
2x -y = 6
2x - 2 = 6
Collecting like terms
2x = 6 + 2
2x = 8
Dividing by 2
x = 8/2
x = 4
