Anyone able to help me with this???? Need it ASAP!! Please and thank youuu

Answer 1

(4, -3)

Explanation:

Rewrite equations:

x−2y=10;6x+3y=15

Step: Solvex−2y=10for x:

x−2y=10

x−2y+2y=10+2y(Add 2y to both sides)

x=2y+10

Step: Substitute2y+10forxin6x+3y=15:

6x+3y=15

6(2y+10)+3y=15

15y+60=15(Simplify both sides of the equation)

15y+60+−60=15+−60(Add -60 to both sides)

15y=−45

15y

15

=

−45

15

(Divide both sides by 15)

y=−3

Step: Substitute−3foryinx=2y+10:

x=2y+10

x=(2)(−3)+10

x=4(Simplify both sides of the equation)

Therefore answer: is

x=4 and y=−3

Hope it helps!
