Question

​
−4x+3y=−2
y=x−1
​ i need x and y

Answer 1

Rewrite equations:

y=x−1;−4x+3y=−2

Step: Solvey=x−1for y:

y=x−1

Step: Substitutex−1foryin−4x+3y=−2:

−4x+3y=−2

−4x+3(x−1)=−2

−x−3=−2(Simplify both sides of the equation)

−x−3+3=−2+3(Add 3 to both sides)

−x=1

−x

−1

=

1

−1

(Divide both sides by -1)

x=−1

Step: Substitute−1forxiny=x−1:

y=x−1

y=−1−1

y=−2(Simplify both sides of the equation)

Answer:

x=−1 and y=−2
