Solve 6800=(680-m)(-0.2)

$$6800 = ( 680 - m ) ( - 0.2 )$$

Solve for m

$$m=34680$$

Steps for Solving Linear Equation

Divide both sides by -0.2.

$$\frac{6800}{-0.2}=680-m$$

Expand \frac{6800}{-0.2} by multiplying both numerator and the denominator by 10.

$$\frac{68000}{-2}=680-m$$

Divide 68000 by -2 to get -34000.

$$-34000=680-m$$

Swap sides so that all variable terms are on the left hand side.

$$680-m=-34000$$

Subtract 680 from both sides.

$$-m=-34000-680$$

Subtract 680 from -34000 to get -34680.

$$-m=-34680$$

Multiply both sides by -1.

$$m=34680$$
