Answer:

9x+8=23      HOPE THIS HELPS

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

17+7x−9=19−2x+4

17+7x+−9=19+−2x+4

(7x)+(17+−9)=(−2x)+(19+4)(Combine Like Terms)

7x+8=−2x+23

7x+8=−2x+23

Step 2: Add 2x to both sides.

7x+8+2x=−2x+23+2x

9x+8=23

Step 3: Subtract 8 from both sides.

9x+8−8=23−8

9x=15

Step 4: Divide both sides by 9.

9x /9 = 15 /9

x= 5 /3
