Solve the equation 3xy+4=8y-2x for x in terms of y

x =

Step-by-step explanation:

Given

3xy + 4 = 8y - 2x ( add 2x to both sides )

3xy + 2x + 4 = 8y ( subtract 4 from both sides )

3xy + 2x = 8y - 4 ← factor out x from each term on the left side

x(3y + 2) = 8y - 4 ← divide both sides by (3y + 2)

x =

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
