Answer:

22

Step-by-step explanation:

(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)

Then add the similar things together

5x+4x=9x

-7-11= -18

9x-18=180, add 18 on both sides to get 9x alone

9x=180, then divide 180 by 9 to get x alone

x=22

PLEASE HELLLP!!!!! If x+7=2y and y=2x−1, what is the value of y? (NOT 13)
oee [108]

Answer:

(C) 5

Step-by-step explanation:

x+7=2y

<em>Subtract 7 from both sides</em>

x=2y-7

2y-7=x

<em>Multiply both sides by 2</em>

4y-14=2x

y=2x−1

<em>Add 1 to both sides</em>

y+1=2x

<u>Combine equations:</u>

y+1=4y-14

<em>Add 14 to both sides</em>

y+15=4y

<em>Subtract y from both sides</em>

15=3y

3y=15

<em>Divide both sides by 3</em>

y=5

<u>The answer is </u><u>(C) 5.</u>
