Question

Solve each of the following pairs of equations by the elimination method.
$8x+5y=9$
$3x+2y=4$

Answer 1

$8x+5y=\mathrm{4...........}\left(i\right)$

$93x+2y=\mathrm{4..........}\left(ii\right)$

Multiply $\left(i\right)$ by $2$ and $\left(ii\right)$ by $5$

$16x+10y=8$

$465x+10y=20$

Subtract both the equations

$449x=12$

$x=\frac{12}{449}$

$y=\frac{340}{449}$
