Solve 1.8=(0.8)x+50.8^2

$$1.8=(0.8)x+5 { 0.8 }^{ 2 }$$

Solve for x

$$x=-1.75$$

Steps for Solving Linear Equation

Calculate 0.8 to the power of 2 and get 0.64.

$$1.8=0.8x+5\times 0.64$$

Multiply 5 and 0.64 to get 3.2.

$$1.8=0.8x+3.2$$

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

$$0.8x+3.2=1.8$$

Subtract 3.2 from both sides.

$$0.8x=1.8-3.2$$

Subtract 3.2 from 1.8 to get -1.4.

$$0.8x=-1.4$$

Divide both sides by 0.8.

$$x=\frac{-1.4}{0.8}$$

Expand \frac{-1.4}{0.8} by multiplying both numerator and the denominator by 10.

$$x=\frac{-14}{8}$$

Reduce the fraction \frac{-14}{8} to lowest terms by extracting and canceling out 2.

$$x=-\frac{7}{4}$$
