Answer:x=7, \ y=-2

Step-by-step explanation:

Given

Equations are 3x-y=23 and 2x+3y=8

take 3x-y=23

y=3x-23

Put the value of y in another equation

\Rightarrow 2x+3(3x-23)=8\\\Rightarrow 2x+9x-69=8\\\Rightarrow 11x=77\\\Rightarrow x=7

Put the value of x in y

y=3(7)-23=21-23=-2

Hence, x=7, \ y=-2

Answer:

b. 28x + 8y +2

Step-by-step explanation:

you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.

-2*3x= -6x

-2*12y= -24y

-2*-5= 10 (remember neg times neg = pos)

-2*17= 34x

-2*-16y=32y

-2*4= -8

Now combine like terms

34x-6x= 28x

32y-24y=8y

10-8=2

Write the expression:  28x + 8y +2
