Solve (1.3x*30+1.3x*0.8*20)div50=1

$$(1.3x \times 30+1.3x \times 0.8 \times 20) \div 50=1$$

Solve for x

$$x=\frac{250}{299}\approx 0.836120401$$

Steps for Solving Linear Equation

Multiply both sides by 50.

$$1.3x\times 30+1.3x\times 0.8\times 20=50$$

Multiply 1.3 and 30 to get 39.

$$39x+1.3x\times 0.8\times 20=50$$

Multiply 1.3 and 0.8 to get 1.04.

$$39x+1.04x\times 20=50$$

Multiply 1.04 and 20 to get 20.8.

$$39x+20.8x=50$$

Combine 39x and 20.8x to get 59.8x.

$$59.8x=50$$

Divide both sides by 59.8.

$$x=\frac{50}{59.8}$$

Expand \frac{50}{59.8} by multiplying both numerator and the denominator by 10.

$$x=\frac{500}{598}$$

Reduce the fraction \frac{500}{598} to lowest terms by extracting and canceling out 2.

$$x=\frac{250}{299}$$
