Answer:

Luke is wrong because 4r + 5 + 2r = 6r+5.

You can only add numbers with the same variable, 4r and 2r have the same variable so they can be added while 5 does not have a variable, this means it cannot be added to 4r and 2r.

Step-by-step explanation:

4r + 5 + 2r

4<u>r</u> + 2<u>r</u> + 5

6r + 5

-7x - 2y = 19<br> 4x + y = -12<br> Solve the system
nalin [4]

-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)
