Find the value of x.

24

Step-by-step explanation:

=> 5x+2+2x+10 = 180 (Angles on a straight line add up to 180)

=> 7x+12 = 180

=> 7x = 180-12

=> 7x = 168

Dividing both sides by 7

=> x = 24

x= 24

Step-by-step explanation:

(5x +2)° +(2x +10)°= 180° (adj. ∠s on a str. line)

5x+2 +2x +10= 180

7x +12= 180 (simplify)

7x= 180 -12 (-12 on both sides)

7x= 168

x= 168 ÷7

x= 24

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
