Solve the following system of equations below 4x+y=16 2x+3y=-2
1 answer:
<h3>
answer:</h3>
x = 5
y = -4
<h3>
steps:</h3>
4x + y = 16
multiply 2nd equation by 2
4x + 6y = -4
subtract equations
0 -5y = 20
-5y = 20
y = 20 ÷ -5
y = -4
substitute y = -4 to find the value of x
4x + (-4) = 16
4x - 4 = 16
4x = 20
x = 5
