Answer:

x = 4, y = 2

Step-by-step explanation:

The 2 equations are:

10x + 4y = 48   (1)
−2x + 10y = 12  (2)

multiplying (2) by 5 gives us
-10x + 50 y = 60   (3)

(1) + (3) will cancel out the x coefficients and gives us
54y = 108 or y =2  

Substituting for y in equation (1) gives us

10x + 4.2  = 48 ==>

10x = 48-8 ==>

10x =  40 or x =4
