Solve 63*(-14/9)+(-1/7)=(-0.9)

$$63 \times ( - 1 \frac { 4 } { 9 } ) + ( - \frac { 1 } { 7 } ) = ( - 0.9 )$$

Verify

Solution Steps

Multiply both sides of the equation by 63, the least common multiple of 9,7.

$$3969\left(-\frac{1\times 9+4}{9}\right)-9=-56.7$$

Multiply 1 and 9 to get 9.

$$3969\left(-\frac{9+4}{9}\right)-9=-56.7$$

Add 9 and 4 to get 13.

$$3969\left(-\frac{13}{9}\right)-9=-56.7$$

Express 3969\left(-\frac{13}{9}\right) as a single fraction.

$$\frac{3969\left(-13\right)}{9}-9=-56.7$$

Multiply 3969 and -13 to get -51597.

$$\frac{-51597}{9}-9=-56.7$$

Divide -51597 by 9 to get -5733.

$$-5733-9=-56.7$$

Subtract 9 from -5733 to get -5742.

$$-5742=-56.7$$

Compare -5742 and -56.7.

$$\text{false}$$
