Answer 2

Solve y=x;6y=−2x−3
Steps:
I will try to solve your system of equations.
y=x;6y=−2x−3
Step: Solvey=xfor y:
Step: Substitutexforyin6y=−2x−3:
6y=−2x−3
6x=−2x−3
6x+2x=−2x−3+2x(Add 2x to both sides)
8x=−3
8x8=−38(Divide both sides by 8)
x=−38
Step: Substitute−38forxiny=x:
y=x
y=−38
Answer:
y=−3/8 and x=−3/8
