Question

4) 4x + 3y = 56
2x + y = 24
Solve using elimination please show work

Answer 1

x = 8 y = 8

Explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now 4x + 3y = 56

-6x - 3y = -72

-2x = -16

x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check: Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56 So we have the correct values for x and y
