If 12y=75+5x+2x-1. What is the value of x

AleksandrR [38]

Answer:

x = $\frac{12y - 74}{7}$

Step-by-step explanation:

12y = 75 + 5x + 2x - 1

combine like terms:

12y = 74 + 7x

subtract 74 from both sides:

7x = 12y - 74

divide both sides by 7:

x = $\frac{12y - 74}{7}$

Identify the constant of proportionality for each direct variation below.

andriy [413]

Answer:

see explanation

Step-by-step explanation:

The equation of 2 quantities in direct proportion is

y = kx ← k is the constant of proportionality

y = - 4x ← in standard form

with k = - 4

$\frac{y}{x}$ = 2 ( multiply both sides by x )

y = 2x ← in standard form

with k = 2

$\frac{x}{y}$ = 3 ( multiply both sides by y )

x = 3y ( divide both sides by 3 )

$\frac{1}{3}$ x = y ← in standard form

with k = $\frac{1}{3}$
