Answer:
x=4
Explanation:
distribute-
2x+15x-21=47
combine like terms-
17x-21=47
add 21 to both sides
17x=68
Divide 17 from both sides
Answer: PLZ Mark me Brainiest
Step 1: Simplify both sides of the equation.
2x+3(5x−7)=47
2x+(3)(5x)+(3)(−7)=47(Distribute)
2x+15x+−21=47
(2x+15x)+(−21)=47(Combine Like Terms)
17x+−21=47
17x−21=47
Step 2: Add 21 to both sides.
17x−21+21=47+21
Step 3: Divide both sides by 17.
17x
17
=
68
