Question

3(x-5)+11=2y+17
5X+2(y-3)=30-X
Trebuie pus in acolada mare

Answer 1

${3(x - 5) + 11 = 2y + 17$

${5x + 2(y - 3) = 30 - x$

$= >$

{Y=

$- \frac{21}{2} + \frac{3}{2} x$

${5x + 2(y - 3) = 30 - x$

$= >$

$5x + 2( - \frac{21}{2} + \frac{3}{2} x - 3) = 30 - x = >$

$x = \frac{19}{3}$

$y = - \frac{21}{2} + \frac{3}{2} \times \frac{19}{3} = >$

$y = - 1$

$= >$

$(x.y) = ( \frac{19}{3} . - 1)$

Sa faci o acoladă mare in fața celor 2 ecuații pt că e sistem
