Answer:

x = 2

Step-by-step explanation:

On the left-hand side we have 3 x's and 8 boxes of 1; therefore, we can write

3 x + 8

On the right-hand side, we have 4 x's and 6 boxes of 1 which we can represent as

4x + 6

Placing the equality sign in between gives

3x + 8 = 4x + 6

subtracting 4x from both sides gives

3x + 8 -4x = 4x + 6 -4x

----> -x + 8 = 6

Finally, subtracting 8 from both sides gives

-x + 8 - 8 = 6 -8

-x = -2

multiplying both sides by -1 gives

x = 2.
