Answer: x=-3/5 y=-41/5
Step-by-step explanation: Rewrite equations:
y=12x−1;4x−2y=14
Step: Solvey=12x−1for y:
y=12x−1
Step: Substitute12x−1foryin4x−2y=14:
4x−2y=14
4x−2(12x−1)=14
−20x+2=14(Simplify both sides of the equation)
−20x+2+−2=14+−2(Add -2 to both sides)
−20x=12
−20x
−20
=
12
−20
(Divide both sides by -20)
x=
−3
5
Step: Substitute
−3
5
forxiny=12x−1:
y=12x−1
y=12(
−3
5
)−1
y=
−41
5
(Simplify both sides of the equation)
