Thread: Simultaneous equation problem

Use the method of elimination to solve the following simultaneous equations.
-5p+q/2=-3/2
2p+3q/2=4

What are the following steps?

To eliminate p, multiply the first equation by two, the second by 5 and add the results.

-5p+q/2=-3/2......(1)
2p+3q/2=4......(2)

(1)x2
(-5p)x2+(q/2)x2=(-3/2)x2
-10p+q=-3

(2)x5
(2p)x5+(3q/2)x5=(4)x5
10p+15q/2=20

(-10p+q)+(10p+15q/2)=-3+20
16q/2=17

Then

Thx for ur help.
My answer booklet's answer is q=-2 and p=1
After I follow ur method to do, I also got the q=2 answer.
Is there are somethin' wrong??
