Solve Ed=2.8/10*7-10/3.3-2.8

$$E d = \frac { 2.8 } { 10 } \times \frac { 7 - 10 } { 3.3 - 2.8 }$$

Solve for E

$$E=-\frac{42}{25d}$$

$$d\neq 0$$

Steps for Solving Linear Equation

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

$$Ed=\frac{28}{100}\times \frac{7-10}{3.3-2.8}$$

Reduce the fraction \frac{28}{100} to lowest terms by extracting and canceling out 4.

$$Ed=\frac{7}{25}\times \frac{7-10}{3.3-2.8}$$

Subtract 10 from 7 to get -3.

$$Ed=\frac{7}{25}\times \frac{-3}{3.3-2.8}$$

Subtract 2.8 from 3.3 to get 0.5.

$$Ed=\frac{7}{25}\times \frac{-3}{0.5}$$

Expand \frac{-3}{0.5} by multiplying both numerator and the denominator by 10.

$$Ed=\frac{7}{25}\times \frac{-30}{5}$$

Divide -30 by 5 to get -6.

$$Ed=\frac{7}{25}\left(-6\right)$$

Multiply \frac{7}{25} and -6 to get -\frac{42}{25}.

$$Ed=-\frac{42}{25}$$

The equation is in standard form.

$$dE=-\frac{42}{25}$$

Divide both sides by d.

$$\frac{dE}{d}=-\frac{\frac{42}{25}}{d}$$

Dividing by d undoes the multiplication by d.

$$E=-\frac{\frac{42}{25}}{d}$$

Divide -\frac{42}{25} by d.

$$E=-\frac{42}{25d}$$

Solve for d

$$d=-\frac{42}{25E}$$

$$E\neq 0$$
