Solve 0.690+60=1.4left(0.4x+90-60right)

$$0.690+60 = 1.4 \left( 0.4x+90-60 \right)$$

Solve for x

$$x=33.375$$

Steps for Solving Linear Equation

Add 0.69 and 60 to get 60.69.

$$60.69=1.4\left(0.4x+90-60\right)$$

Subtract 60 from 90 to get 30.

$$60.69=1.4\left(0.4x+30\right)$$

Use the distributive property to multiply 1.4 by 0.4x+30.

$$60.69=0.56x+42$$

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

$$0.56x+42=60.69$$

Subtract 42 from both sides.

$$0.56x=60.69-42$$

Subtract 42 from 60.69 to get 18.69.

$$0.56x=18.69$$

Divide both sides by 0.56.

$$x=\frac{18.69}{0.56}$$

Expand \frac{18.69}{0.56} by multiplying both numerator and the denominator by 100.

$$x=\frac{1869}{56}$$

Reduce the fraction \frac{1869}{56} to lowest terms by extracting and canceling out 7.

$$x=\frac{267}{8}$$
