Answer:

y = 4/5x - 9/5

Step-by-step explanation:

4x - 5y = 9 to solve for y you get it by itself.

-4x -4x minus 4x from both sides

-5y = - 4x + 9

/-5 /-5 Divide both sides by 5

y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

$C = \frac{5}{9} (F - 32)$

Multiply both sides by 9

$9C = \frac{5(9)}{9} (F - 32)$

Simplify

$9C = 5(F - 32)$

Divide both sides by 5

$\frac{9}{5} C = \frac{5}{5} (F - 32)$

Simplify

$\frac{9}{5} C = F -32$

Add 32 in both sides

$\frac{9}{5} C + 32 = F - 32 + 32$

Simplify (Inverse)

$\frac{9}{5} C + 32 = F$

Substitute to find F

$\frac{9}{5} (26) + 32 = F$

Simplify

F = 46.8 + 32

Result

F = 78.8
