Solve 1525+1*7x>4.2x

$$1525+1 \cdot 7x > 4.2x$$

Solve for x

$$x>-\frac{7625}{14}$$

Solution Steps

Multiply 1 and 7 to get 7.

$$1525+7x>4.2x$$

Subtract 4.2x from both sides.

$$1525+7x-4.2x>0$$

Combine 7x and -4.2x to get 2.8x.

$$1525+2.8x>0$$

Subtract 1525 from both sides. Anything subtracted from zero gives its negation.

$$2.8x>-1525$$

Divide both sides by 2.8. Since 2.8 is positive, the inequality direction remains the same.

$$x>\frac{-1525}{2.8}$$

Expand \frac{-1525}{2.8} by multiplying both numerator and the denominator by 10.

$$x>\frac{-15250}{28}$$

Reduce the fraction \frac{-15250}{28} to lowest terms by extracting and canceling out 2.

$$x>-\frac{7625}{14}$$
