Question

$\\ x- \frac{y+1}{2}=0 \\ \\ \frac{x}{2} + \frac{y}{5} =2$

Resolver ecuación por método de sustitución

Answer 1

$x = \frac{y+1}{2}$

$\frac{1}{2} ( \frac{y+1}{2} )+ \frac{y}{5} = 2$

$\frac{y}{4} + \frac{1}{4} + \frac{y}{5} = 2$

$\frac{9y}{20} = \frac{7}{4}$

$9y = 35$

$y = \frac{35}{9}$


$x = \frac{1}{2} ( \frac{35}{9} +1)$

$x = \frac{22}{9}$
