Solve the system of equations by substitution.
x+y=32
y=7x

x=4

Step-by-step explanation:

since y=7x

x+7x=32

8x=32

x=4

x=4

Step-by-step explanation:

x+y=32

y=7x

Since Y can be replaced by 7x, substitute into eq1.

x+y( notice y can be replaced by 7x) =32

x+7x=32 ( Y got replaced

8x=32

Divide 8 on both sides.

x=4

Hope this helps plz hit the crown :D
