Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
3 0

Answer:

y= -3y - 1/3x

Step-by-step explanation:

-2(x + 3y) = 18 Distribute the -2 to the x + 3y

-2x - 6y = 18

+2x          +2x    Add the 2x to both sides

-6y = 18 + 2x   Divide both sides by -6

y= -3y - 1/3x

2(2x +1) = 3(x-8) =<br>how do you solve this ​
saw5 [17]

Answer:

x=-26

Step-by-step explanation:

Distributive property first (both sides)

you would get

4x+2 = 3x-24

next you will subtract 3x from both sides

1x+2=-24

add 24 to both sides

1x+26=0

move 26 to the other side but since you flipped it you have to make it negative

x=-26
