solve the following system of equations using substitution.
show all work

y=x+8
y=4x+5

(1, 9 )

Step-by-step explanation:

Given the 2 equations

y = x + 8 → (1)

y = 4x + 5 → (2)

Substitute y = 4x + 5 into (1)

4x + 5 = x + 8 ( subtract x from both sides )

3x + 5 = 8 ( subtract 5 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting in (1)

y = 1 + 8 = 9

Solution is (1, 9 )

where are the choices?
