Question

Pls help it's Substitution (Level 3)

Answer 1

Answer:

x=−1 and y=3

Step-by-step explanation:

Let's solve your system by substitution.

x=−y+2;4x−6y=−22

Step: Solve x=−y+2 for x:

x=−y+2

Step: Substitute−y+2for x in 4x−6y=−22:

4x−6y=−22

4(−y+2)−6y=−22

−10y+8=−22(Simplify both sides of the equation)

−10y+8+−8=−22+−8(Add -8 to both sides)

−10y=−30

−10y

−10

=

−30

−10

(Divide both sides by -10)

y=3

Step: Substitute 3 for y in x=−y+2:

x=−y+2

x=−3+2

x=−1 (Simplify both sides of the equation)

Answer:

x=−1 and y=3
