Question

6x+y-31=0,
3x+2y-26=0
​

Answer 1

Question:-

6x+y-31=0

3x+2y-26=0

Solve for x and y.

Answer:-

Rearranging, 6x+y=31 --A

3x+2y=26 --B

Multiply B by 2... => 6x+4y=52 --C

Now, C-A => 6x-6x + 4y-y = 52-31

0 + 3y = 21

y =21/3

y =7

Sub in A => 6x+7=31

6x=31-7

x=24/6

x=4

Therefore, we get x=4 and y=7 .
