Blanche needs to solve the system of equations below.
4 + 4 = β7 β12 β 3 = β24
She decides to use the elimination method to cancel out the βxβ term in order to first solve for βyβ. Blanche uses the following steps:
Did Blanche use the correct steps to solve for βyβ?
Step 1.
Step 2.
Step 3. Step 4.
3(4) + 4 = β7 β12 β 3 = β24
12 + 4 = β7 β12 β 3 = β24
= β31
So then = β31
