Answer:
x = 1
Each green rectangle has a value of 1.
Explanation:
Left Side:
On the left side there are 7 green rectangle worth x each.
The total value of the green rectangles on the left is 7x.
Then there are 9 small yellow squares worth 1 each.
The total value of the small yellow squares at left is 9.
The total value of the left side is
7x + 9
Right Side:
On the right side there are 2 green rectangle worth x each.
The total value of the green rectangles on the right is 2x.
Then there are 14 small yellow squares worth 1 each.
The total value of the small yellow squares at right is 14.
The total value of the right side is
2x + 14
The equal sign shows that the value of the left side equals the value of the right side.
7x + 9 = 2x + 14
Subtract 2x from both sides.
5x + 9 = 14
Subtract 9 from both sides.
5x = 5
Divide both sides by 5.
x = 1
Each green rectangle has a value of 1.
