Question

4x-2y= 12
5x+2y= 106 find x and y by substitution method

Answer 1

buddy this is your answer

Answer 2

in eq 1,
4x=12+2y
x=12+2y/4. (eq 3)

putting value of x in eq 2
5(12+2y/4)+2y=106
60+10 y/4+2y=106
60 +10y+8y/4=106
60+18y=106×4
18y=424-60
18y=346
y=346/18

putting value of y in eq 3

x=12+2y/4
=12+2(346÷18)/4
=12+692÷72
=704÷12
60+10y/4+2y=106
60+
