Question

Solve the pair of equation x-y=3 and 2x+3y=36

Answer 1

Answer:

x=9 and y=6

Step-by-step explanation:

x-y=3 (now multiply by 2)

2x-2y=6

Subtract this from 2x+3y=36

2x+3y=36

2x-2y=6 (-)

2x+3y=36 - 2x+2y= - 6

5y=36-6=30

y=30÷5 =6//

x-y=3

x-6=3

x=6+3=9//

Now that's your answer...

God bless you..
