Question

2x+3r=6
x+4r=4 i kneed onl one answers

Answer 1

2x+3r=6
⇒2x=6-3r
⇒x=$\frac{6-3r}{2}$.....(1)
x+4r=4
substituting the value of x as $\frac{6-3r}{2}$ from....(1) we get:
$\frac{6-3r}{2}$ +4r=4
⇒6-3r+4r * 2 =4*2
⇒6-3r+8r=8
⇒5r=8-6
⇒r=$\frac{2}{5}$
Substituting the value of r as $\frac{2}{5}$ we get:
x+4r=4
⇒x=4-4r
⇒x=4-$\frac{2*4}{5}$
⇒x=4-$\frac{8}{5}$
⇒x=$\frac{12}{5}$
Ans:x=$\frac{12}{5}$
r=$\frac{2}{5}$
