Solve the following system of equations using the substitution method:

\[
2a = 8 \\
a + b = 2
\]

2a=8 /:2 a=4
a+b=2 4+b=2 b=2-4 b=-2
I hope this is the answer you were looking for.

The solution to the system of equations is a = 4 and b = − 2 . Using substitution, we first solved for a from the first equation and then substituted it into the second equation to find b . The final answer is the ordered pair ( 4 , − 2 ) .
