x = 5, y = 15

Step-by-step explanation:

1st option: x=5 and y=15

Step-by-step explanation:

Let's solve your system by substitution.

3x+2y=45;4x−y=5

Rewrite equations:

4x−y=5;3x+2y=45

Step: Solve4x−y=5for y:

4x−y=5

4x−y+−4x=5+−4x(Add -4x to both sides)

−y=−4x+5

−y

−1

=

−4x+5

−1

(Divide both sides by -1)

y=4x−5

Step: Substitute4x−5foryin3x+2y=45:

3x+2y=45

3x+2(4x−5)=45

11x−10=45(Simplify both sides of the equation)

11x−10+10=45+10(Add 10 to both sides)

11x=55

11x

11

=

55

11

(Divide both sides by 11)

x=5

Step: Substitute5forxiny=4x−5:

y=4x−5

y=(4)(5)−5

y=15(Simplify both sides of the equation)
