Solve for y
-12=-3+3y
Simplify your answer as much as possible.

Y=

-9=3y

Step-by-step explanation:

-12=-3+3y

+3 +3

-9=3y

y=-3

Step-by-step explanation:

First you wanna move your -3 to the other side to isolate y. To do this, add 3 to both sides since you were. originally subtracting it. After doing this you get -9=3y. Now you'll want to divide both sides by 3 since you want to isolate y and 3 is being multipliied by y so you'll want to do the opposite and divide both sides by 3 to get y=-3.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
