Question

1. Solve the following system: 2x + 2y = 38 y = x + 3

Answer 1

Answer:

y=11

x=8

Step-by-step explanation:

This is Elimination

2x+2y=38

Subtract 2x on both sides   2y=-2x+38

Then Multiply 2(y=x+3)  which equals 2y=2x+6

Solve by Elimination

2y=-2x+38

2y=2x+6

add the y's and since the x's are different those cancel out, then add 38 and 6.

then you do the equation 4y=44

divide both by 4

y=11

then you do 11=x+3

subtract 3 on both sides

x=8

and there you go

I hope this is how you wanted it solved
