Question

Y = 1/2x + 4 x - y = 8 *Substitution

Answer 1

Answer:

y=16, x=24

Step-by-step explanation:

First simplify: x-(1/2x+4)=8

Isolate x for 1/2x-4=8

Add 4 to both sides:

1/2-4+4=8+4

Simplify :1/2=12

Multiply both sides by 2:

2*1/2x=12*2

Simplify:

x=24

Substitute x=24:

y=1/2*24+4

1/2*24+4=16

1/2*24=12

12+4

Add the numbers: 12+4=16

y=16

The solutions to the systems of equations are:

y=16,x=24
