2a+3b = -1 | *3
3a +5b = -2 |* -2
6a+ 9b = -3
-6a -10b = 4
------------------
/ -b =1
b= -1
2a + 3b= -1
2a + 3* -1 = -1
2a -3= -1
2a = 3-1
2a=2
a=2:2
a=1
Given:
The equation is

To find:
The solution of given equation.
Solution:
We have,

Using distributive property, we get



Adding 7 on both sides, we get


Divide both sides by 4.
