Answer:
x = 4 and y = -2
Step-by-step explanation:
Let 6x - 2y = 28 be equation (i)
and 4x + 2y = 12 be equation (ii)
To solve the following equations, first add the equations:
6x - 2y + 4x + 2y = 28 + 12
6x + 4x + 2y - 2y = 28 + 12
10 x = 40
x = 4
Substituting in (ii)
4x + 2y = 12
4*4 + 2y = 12
2y = 12 - 16
2y = -4
y = -2
