Respuesta :
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 <==
-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]
