2x-3y=9..............1
4x+6y=10............2
Multiply equation 1 from 6 and equation3 from 2
------------------
12x-18y=54...........3
12x+18y=30...........4
Add equation 3 and 4
------------------
24x=84
x=84÷24
x=3.5
put x = 3.5 in equation 1
2x-3y=9
2(3.5)-3y=9
7-3y=9
-3y=9-7
-3y=2
y=2÷3
This is the answer
