Answer:

Equation: 3x - 4 = 6 - 2x

Solution: x = 2

Explanation:

Look at the key.

Left side of the equal sign:

A grey rectangle means x.

There are 3 grey rectangles on the left side, so that is 3x.

A white square means -1.

There are 4 white squares on the left side, so that means -4.

Altogether, the left side is 3x - 4.

Right side of the equal sign:

A black square means 1.

There are 6 black squares, so that means 6.

A white rectangle means -x.

There are 2 white rectangles, so that means -2x.

Altogether, the right side is 6 - 2x.

Put both sides together, and you have

3x - 4 = 6 - 2x

Solve the equation:

Add 2x to both sides.

5x - 4 = 6

Add 4 to both sides.

5x = 10

Divide both sides by 5.

x = 2

Answer:

Equation: 3x - 4 = 6 - 2x

Solution: x = 2
