Solve 9x2+15:3+4+12:4*2-3*3*2

$$9 x 2 + 15 : 3 + 4 + 12 : 4 \times 2 - 3 \times 3 \times 2$$

Evaluate

$$9x_{2}-3$$

Solution Steps

Divide 15 by 3 to get 5.

$$9x_{2}+5+4+\frac{12}{4}\times 2-3\times 3\times 2$$

Add 5 and 4 to get 9.

$$9x_{2}+9+\frac{12}{4}\times 2-3\times 3\times 2$$

Divide 12 by 4 to get 3.

$$9x_{2}+9+3\times 2-3\times 3\times 2$$

Multiply 3 and 2 to get 6.

$$9x_{2}+9+6-3\times 3\times 2$$

Add 9 and 6 to get 15.

$$9x_{2}+15-3\times 3\times 2$$

Multiply 3 and 3 to get 9.

$$9x_{2}+15-9\times 2$$

Multiply 9 and 2 to get 18.

$$9x_{2}+15-18$$

Subtract 18 from 15 to get -3.

$$9x_{2}-3$$

Factor

$$3\left(3x_{2}-1\right)$$

Solution Steps

Multiply and combine like terms.

$$9x_{2}-3$$

Factor out 3.

$$3\left(3x_{2}-1\right)$$
