Answer:

  • x = -15

Explanation:

Given :

  • 4 + 5x + 66 = x + 10

#1 : Combine like terms on each side.

  • 4 + 5x + 66 = x + 10
  • 5x + 70 = x + 10

#2 : Subtract x from each side.

  • 5x + 70 - x = x + 10 - x
  • 4x + 70 = 10

#3) Subtract 70 from each side.

  • 4x + 70 - 70 = 10 - 70
  • 4x = -60

#4) Divide 4 from each side.

  • 4x/4 = -60/4
  • x = -15

Solution : x = -15

Hey there!

4 + 5x + 66 = x + 10

70 + 5x = x + 10

5x + 70 = x + 10

SUBTRACT x to BOTH SIDES

5x + 70 - x = x + 10 - x

5x + 70 - 1x = 1x + 10 - 1x

SIMPLIFY IT!
4x + 70 = 10

SUBTRACT 70 to BOTH SIDES

4x + 70 - 70 = 10 - 70

SIMPLIFY IT!
4x = -60

DIVIDE 4 to BOTH SIDES

4x/4 = -60/4

SIMPLIFY IT!
x = -60/4

x = -15


Therefore, your answer is: x = -15


Good luck on your assignment & enjoy your day!
