Answer:

33

Step-by-step explanation:

Rewrite the bottom expression:

-2a-2b-2c-3x-3y

Factor the expression into two parts:

-2(a+b+c) + -3(x+y)

Substitute -3 for a+b+c and -9 for x+y:

-2(-3) + -3(-9)

6 + 27

33

Therefore, your final answer is 33

Solve the simultaneous equations<br> 2x+3y20 <br> 2x+5=10

Answer:

$x=\frac{5}{2} \\y=5$

( 5/2, 2 )

Step-by-step explanation:

Solve by substitution method:

$2x+5=10\\\2x+3y=20$

Solve $2x+5=10$ for $x$ :

$2x+5=10$

$2x=10-5$

$2x=5$

$x=5/2$

Substitute $5/2$ for $x$ in $2x+3y=20$ :

$2x+3y=20$

$2(\frac{5}{2} )+3y=20$

$3y+5=20$

$3y=20-5$

$3y=15$

$y=15/3$

$y=5$

∴ $x=\frac{5}{2}$ and $y=5$
