Solve 3*0.4+2*5.4y=1

$$3 \times 0.4+2 \times 5.4y=1$$

Solve for y

$$y=-\frac{1}{54}\approx -0.018518519$$

Steps for Solving Linear Equation

Multiply 3 and 0.4 to get 1.2.

$$1.2+2\times 5.4y=1$$

Multiply 2 and 5.4 to get 10.8.

$$1.2+10.8y=1$$

Subtract 1.2 from both sides.

$$10.8y=1-1.2$$

Subtract 1.2 from 1 to get -0.2.

$$10.8y=-0.2$$

Divide both sides by 10.8.

$$y=\frac{-0.2}{10.8}$$

Expand \frac{-0.2}{10.8} by multiplying both numerator and the denominator by 10.

$$y=\frac{-2}{108}$$

Reduce the fraction \frac{-2}{108} to lowest terms by extracting and canceling out 2.

$$y=-\frac{1}{54}$$
