Easy explanation of substitution |
|
Answer» Substitution means subsituting the value of one variable in the other equation to find the value of other variable. For example :x+y=2 .......(1)x-y=3. ..........(2)We can write equation (2) as x=3+y. ........(3)Now put the value of x in eq. (1)x+y=2(3+y)+y=23+2y=22y=2-3y=-1/2Substituting value of y in equation 2x-y=3x-(-1/2)=3x+1/2=32x+1/2=32x+1=62x=5x=5/2Hence we get value of x and y by substituting value of x to find the value of y. Substitution is itself so easy. |
