Answer: x = 11 + y

Step-by-step explanation: Simplifying

4x + -4y = 44

Solving

4x + -4y = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

4x + -4y + 4y = 44 + 4y

Combine like terms: -4y + 4y = 0

4x + 0 = 44 + 4y

4x = 44 + 4y

Divide each side by '4'.

x = 11 + y

Simplifying

x = 11 + y

The value of x in the expression is 3

Using the expressions given :

  • 4x+4y=44 ___(1)
  • y=2x+2 ___(2)

substitute (2) into (1) ;

4x + 4(2x + 2) = 44

4x + 8x + 8 = 44

12x + 8 = 44

12x = 36

x = 36/12

x = 3

The value of x is 3
