Answer:

  1. x = 2/9 ( or 0.2repeating)
  2. x = -2/7 ( or 0.285714 repeating)

Explanation:

there is an equation written in the question and one in the figure, to be sure I'll solve them both

Solve the equation.

7x +(4x - 5) = 3 + 2(x − 3)

7x + 4x - 5 = 3 + 2x - 6

7x + 4x - 2x = 3 - 6 + 5

9x = 2

x = 2/9 ( or 0.2repeating)

----------------------------------------------------------------------

7x + 1/2(4x - 5) = 3/2 + 2(x - 3)

7x + 2x - 5/2 = 3/2 + 2x - 6

7x - 5/2 = 3/2 - 6

14x - 5 = -9/2

14x = -9 + 5

14x = -4

x = -2/7 ( or 0.285714 repeating)
