Question

Im working on algebra hw and i need help with this problem 8.1x - 4.5y = 5.4

Answer 1

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 2

Answer:

The solution for y is $y =\frac{8.1x-5.4}{4.5}$ or $y =1.8x-1.2$

Step-by-step explanation:

Consider the provided equation.

$8.1x - 4.5y = 5.4$

Solve the equation for y.

Subtract 8.1x to the both side.

$- 4.5y = 5.4-8.1x$

Divide both the sides by -4.5

$y =\frac{5.4-8.1x}{-4.5}$

$y =\frac{8.1x-5.4}{4.5}$

or $y =1.8x-1.2$

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