Answer:

4. 21

5.120

Step-by-step explanation:

(the answer for #4

I added 5x+15 and 3x-3

and got

8x+12

and because we needed to find the value of x, l did this

8x+12=180

because interior consecutive angles equal 180

and I got 21

(answer for 5)

I then plugged 21 into 5x+15 because angle 1 is equal to it

5(21)+15

I got 120

-8= 3-5(x+6) solving algebraicaily​
SOVA2 [1]

Let's solve your equation step by step

-8=3-5(x+6)

Step 1: simplify both sides of the equation

-8=3-5(x+6)

-8=3+(-5)(x)+(-5(6) (distribute)

-8=3+-5x+-30

-8=(-5x)+(3+-30) (combine like terms)

-8=-5x+-27

-8=-5x-27

Step 2: flip the equation

-5x-27=-8

Step 3: add 27 to both sides

-5x-27+27=-8+27

-5x=19

Step 4: Divide both sides by -5

-5x/-5 = 19/-5

Answer : x= -19/5
