Equation B tells you what c equals so we sub in c for where it says 3c $\huge ~\rm~3(4d+8)=d-8$

2. anonymous

Distribute the 3 $\huge ~\rm~3(4d+8)$

A system of equations is shown below: n = 3m + 7 n − 2m = 1 What is the solution, in the form (m, n), to the system of equations?

4. anonymous

It tells you what n equals 3m+7-2m=1 combine like terms to get the m value
