Solve 0.65x+0.9(140-x)=85*140

$$0.65x+0.9(140-x)=85 \times 140$$

Solve for x

$$x=-47096$$

Steps for Solving Linear Equation

Use the distributive property to multiply 0.9 by 140-x.

$$0.65x+126-0.9x=85\times 140$$

Combine 0.65x and -0.9x to get -0.25x.

$$-0.25x+126=85\times 140$$

Multiply 85 and 140 to get 11900.

$$-0.25x+126=11900$$

Subtract 126 from both sides.

$$-0.25x=11900-126$$

Subtract 126 from 11900 to get 11774.

$$-0.25x=11774$$

Divide both sides by -0.25.

$$x=\frac{11774}{-0.25}$$

Expand \frac{11774}{-0.25} by multiplying both numerator and the denominator by 100.

$$x=\frac{1177400}{-25}$$

Divide 1177400 by -25 to get -47096.

$$x=-47096$$
