8.1x - 4.5y = 5.4.....subtract 8.1x from both sides
-4.5y = -8.1x + 5.4...divide both sides by -4.5
y = (- 8.1/-4.5)x + 5.4 / -4.5...simplify
y = 1.8x - 1.2 <==

Answer:

The solution for y is [tex]y =\frac{8.1x-5.4}{4.5} [/tex] or [tex]y =1.8x-1.2[/tex]

Step-by-step explanation:

Consider the provided equation.

[tex]8.1x - 4.5y = 5.4[/tex]

Solve the equation for y.

Subtract 8.1x to the both side.

[tex]- 4.5y = 5.4-8.1x [/tex]

Divide both the sides by -4.5

[tex]y =\frac{5.4-8.1x}{-4.5} [/tex]

[tex]y =\frac{8.1x-5.4}{4.5} [/tex]

or [tex]y =1.8x-1.2[/tex]

Hence, the solution for y is [tex]y =\frac{8.1x-5.4}{4.5} [/tex] or [tex]y =1.8x-1.2[/tex]
