Question

-x+y=0
4x-3y=3
substitution

Answer 1

Answer:

x= 3

y= 3

Step-by-step explanation:

Step: Solve−x+y=0 for y:

−x+y=0

−x+y+x=0+x (Add x to both sides)

y=x

Step: Substitute x for y in 4x−3y=3:

4x−3y=3

4x−3x=3

x=3 (Simplify both sides of the equation)

Step: Substitute 3 for x in y=x:

y=x

y=3
