Question

Solve this simultaneous equation:

x+3y=2 and x/3+y/2 =1


Please explain step by step so i understand for future reference.
Thankyou x

Answer 1

first, get rid of those pesky fractions and you have

x+3y = 2
2x+3y = 6

now subtract the 1st from the 2nd and you have

x = 4

Then plug that into either equation to find y:

4+3y = 2
y = -2/3

final step: check those values in each of the original equations to make sure you have not made a mistake somewhere.
