What is the solution to the system of equations give 4x -4y = 16 over x - 2y = -12

x=20, y=8

Explanation:

4x -4y = 16 over x - 2y = -12

x - 2y = -12 multiplying with 2

2x -4y = -24 equation 2

4x -4y = 16 equtaion 1

By substraction equation 2 from 1

4x -4y = 16

-2x  4y = 24 ( signs will change)

2x = 40

x = 40/2

x = 20

By putting the value of x in x - 2y = -12

20 -  2y = -12

20- 2y = -12

20+12 =2y

32=2y

y=32/2

y=8

Cross check

Putting values of both x and y in x - 2y = -12

20- 2(8) = -12

20-32 =-12

-12=-12

so LHS= RHS
