Thank you for the opportunity to help you with your question!

ok for exemple if we have this : 

x + 2y = 1 

3x - y = 2 

so :  we take the first equation :  x + 2y = 1  so x = 1 - 2y so we take the value of x and we put it on the second equation  like : 

3(1 - 2y) - y = 2  so :   3 - 6y - y = 2  so :   - 7y = -1 so :  y = 1/7 

so we put the value of y on the first equation :  x + 2y = 1 

so :  x + 2(1/7) = 2 so :  x = 2 - 2/7  

so :  x = 12/7

tel me if this exemple make you undestand or not ???

Good Luck
