2x-5y=9<br> 3x+4y=2<br> solve the simultaneous equations

wariber [46]

$\huge\boxed{x=2;\ y=-1}$

$\left\{{{2x-5y=9}\atop{3x+4y=2}}\right$

First, we will solve the second equation for $x$ . Subtract $4y$ from both sides of the second equation.

$3x=2-4y$

Divide both sides of the second equation by $3$ .

$x=\frac{2}{3}-\frac{4}{3}y$

$\left\{{{2x-5y=9}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right$

Substitute the value of $x$ from the second equation into the first.

$\left\{{{2(\frac{2}{3}-\frac{4}{3}y)-5y=9}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right$

$2(\frac{2}{3}-\frac{4}{3}y)-5y=9$

We will solve the first equation for $y$ .

Distribute the $2$ to the $(\frac{2}{3}-\frac{4}{3}y)$ .

$\frac{4}{3}-\frac{8}{3}y-5y=9$

Combine the like terms.

$\frac{4}{3}-\frac{23}{3}y=9$

Add $\frac{4}{3}$ on both sides.

$-\frac{23}{3}y=9-\frac{4}{3}$

$-\frac{23}{3}y=\frac{23}{3}$

Divide both sides by $\frac{23}{3}$ .

$-y=1$

Multiply both sides by $-1$ .

$y=\boxed{-1}$

Substitute the value of $y$ into the second equation.

$\left\{{{y=-1}\atop{x=\frac{2}{3}-\frac{4}{3}y}}\right$

$x=\frac{2}{3}-\frac{4}{3}*-1$

Multiply.

$x=\frac{2}{3}+\frac{4}{3}$

Add.

$x=\frac{6}{3}$

$x=\boxed{2}$
