Question

solve the linear system using substitution.
2x=12
x-5y=-29

Answer 1

first divide both sides by 2 in the equation 2x=12

Answer 2

x=6

Answer 3

now, substitute 6 for x in the second equation.
(6)-5y=-29

Answer 4

Subtract 6 from both sides:
-5y=-35

Answer 5

Divide both sides by -5
y=7

Answer 6

Plug in 7 for y to get the x
x-5(7)=-29
x-35=-29
x=6

Answer 7

y=7
x=6

Answer 8

That was a check, because from the first equation you already know that x=6.
