An important and exam oriented question from linear equations in two variables in which we have to find the value of variables x and y from the equations 7(y+3)-2(x+2)=14, 4(y-2)+3(x-3)=2
Kindly give me a detailed solution of this question
RS Aggarwal, Class 10, chapter 3B, question no 15
AfterSimplification
Equation (1) : 2x+7y=−11
Equation (2) : 3x+4y=19
Equation (1)×3 : 6x+21y=−33
Equation (2)×2 : 6x+8y=38
Subtract two equations ;
⇒13y=−71
⇒y=−71/13
Substitute y in equation (1);
⇒x=354/13
