# How do you solve the following linear system:  4x + 3y=31 , 2x+3y=-7 ?

Nov 12, 2015

#### Explanation:

I use elimination method coz it is easy for this kind of question. U can also use subtitution method, u will get the same answer, dont worry.

So, i use minus to eliminate 3y to find x

Be careful when u solve 31 - (-7) = 38

Then, subtitute the answer x=19 into the equation.

U can choose either one of the equation, doesnt matter
