Question

solve these pair of linear equations.. 7x - 8y = 7 , 2x + y = 2​

Answer 1

Answer:

The solutions of this pair of equations are:

x=1

y=0

Step-by-step explanation:

Eq-1___7x-8y=7

Eq-2___2x+y=2

From 2,     y=2-2x

Substituting value of y  in Eq-1:

>>7x-8(2-2x)=7

=7x-16+16x=7

=23x=7+16

=23x=23

>>x=23/23

therefore, x=1

Now, y=2-2x

y=2-2(1)

y=2-2

Therefore, y=0
