Question

solve the following pairs of the linear equations by the method of elimination equating and the coefficients. 3x-y=5 , 3x+2y=8​

Answer 1

subtracting 3x-y=5 from 3x+2y=8 we get

3x+2y-3x-(-y) = 8-5

3x+2y-3x+y = 8-5

3y=3

y = 1

Again

putting value of one in 1 number equation we get

3x-1=5

3x=6

x=2

ANS: x=2 and y=1
