Question

Solve by Substitution method :x-y=3 and 3x+2y+26=0.....I will mark as brainiest

Answer 1

${\red{\huge{\mathcal{\star{Hey{\star}}}}}}$

${\blue{\huge{\boxed{\bf{x=-4}}}}}$

${\blue{\huge{\boxed{\bf{y=-7}}}}}$

steps-

${\bf{\underline{Given:-}}}$

$x - y = 3 \\ 3x + 2y + 26 = 0$

second equation can be written as,

$3x + 2y = - 26$

now from equation 1,

$x = y + 3$

substitute in (2),

$3(3 + y) + 2y = - 26 \\ 9 + 3y + 2y = - 26 \\ 5y = - 9 - 26 \\ 5y = - 35 \\ y = - 7$

substitute the value of y in (1),

$x - ( - 7) = 3 \\ x + 7 = 3 \\ x = 3 - 7 \\ x = - 4$

Hope it helps you ❤✌
