Question

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

Answer 1

y=16.

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 2

y=2(4)+8
y=8+8
y=16
Hope this helps :)
