Answer:
x=2 y=2
Step-by-step explanation:
Rewrite equations:
−6x−y=−14;3x+2y=10
Step: Solve−6x−y=−14for y:
−6x−y=−14
−6x−y+6x=−14+6x(Add 6x to both sides)
−y=6x−14
−y
−1
=
6x−14
−1
(Divide both sides by -1)
y=−6x+14
Step: Substitute−6x+14foryin3x+2y=10:
3x+2y=10
3x+2(−6x+14)=10
−9x+28=10(Simplify both sides of the equation)
−9x+28+−28=10+−28(Add -28 to both sides)
−9x=−18
−9x
−9
=
−18
−9
(Divide both sides by -9)
x=2
