2 answers:
Y=2(4)+8
Answer:
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
