Question

4x-3y=14
x-2y=11 qual e o resultado dessa equaçao

Answer 1

x-3y=14
x-2y=11 -> x=11-2y

x-3y=14
11-2y-3y=14
-2y-3y=14-11
-5y=3 *(-1)
5y=-3
y= $\frac{-3}{5}$

4x-3y=14
4x-3($\frac{-3}{5}$)=14

$\frac{20x}{5} - \frac{15(-3)}{5} = \frac{70}{5}$

20x-15(-3) = 70

20x+45=70
20x=70-45
20x=25
$x= \frac{25}{20}$ (simplificando por 5) $x= \frac{5}{4}$

R: y= $\frac{-3}{5}$
    
    x= $\frac{5}{4}$
