<h3>Question 1</h3>

One fourth of m minus six is equal to two times the sum of m and 9:

  • \dfrac{1}{4}m -6=2(m+9)

This is self-explanatory, please comment if something is unclear.

<h3>Question 2</h3>

Drew has 50 marbles; red, green and blue.

Equation for this:

  • r + g + b = 50

He has six more red marbles than blue marbles:

Equation for this:

  • r = b + 6

He has four fewer green marbles than blue marbles:

Equation for this:

  • g = b - 4

Substitute r and g into first equation and solve for b:

  • r + g + b = 50
  • b + 6 + b - 4 + b = 50
  • 3b + 2 = 50
  • 3b = 48
  • b = 48/3
  • b = 16

Drew has 16 blue marbles.
