Solve the system of equations using substitution. Show your work.
y=3x + 10
y= 5x

x=5 and y=25

Step-by-step explanation:

y=5x

3x+10=5x

3x+10+−5x=5x+−5x(Add -5x to both sides)

−2x+10=0

−2x+10+−10=0+−10(Add -10 to both sides)

−2x=−10

−2x

−2

=

−10

−2

(Divide both sides by -2)

x=5

y=3x+10

y=(3)(5)+10

y=25(Simplify both sides of the equation)
