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
