Solve the equation for me<br> 9y=8(y+11)
IrinaVladis [17]
To start, first distribute 8 to (y+11) which would look something like this:
9y=8y+88
Now, subtract 8y from both sides in order to solve for and isolate the y value. This would result in your answer, y=88.

Y=-3x + 4
serg [7]
Use substitution
Set them equal to each other
-3x + 4 = 3x - 2
Solve the equation
4 = 6x - 2
6x = 6, x = 1
Plug in 1 for any equation to find y
Y = -3(1) + 4
Y = -3 + 4, y = 1
Solution: x = 1, y = 1

3. Triangle ABC has angle measures as shown.
dedylja [7]

The 3 inside angles of a triangle need to equal 180 degrees.

Add the 3 angles together to equal 180:

X + x+2 + 6x +10 = 180

Simplify:

8x + 12 = 180

Subtract 12 from each side:

8x = 168

Divide each side by 8:

x = 168 / 8

X = 21

a) x = 21

b) C = 6x+10

replace x with 21:

6(21) + 10 =

126 +10 = 136
