Using substitution, determine the solution
X=4
and.
y=2x+8

y=16.

Step-by-step explanation:

Using substitution requires us to substitute a value in place of another value. Luckily we are given the value of x and can use it in the second equation.

First, we substitute 4 for x.

y=2(4)+8

And then we simply solve.

y=2(4)+8

y=8+8

y=16

:)))

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.
