Answer 2

Answer:

Step-by-step explanation:

4x - 3y =1

4x =1+3y

x=$\frac{1+3y}{4}$

we will substitute the value of y

⇒5($\frac{1+3y}{4}$ ) - 7y +2 =0

= $\frac{5+15y}{4}$ - $\frac{7y}{1}$ + $\frac{2}{1}$ =0

=$\frac{5+15y-28y+8}{4}$ =0

=$\frac{13-13y}{4}$=0

=13-13y =0

= -13y= -13

=y = $\frac{-13}{-13}$

= y=1

As we know the value of y we can find out the value of x.

x=$\frac{1+3y}{4}$

x=$\frac{1 + 3}{4}$

x= 1
