Alexandra [31]

Answer:

Step-by-step explanation:

Let's say B is the number of boys and T is the number of teachers.

T / (B + 18) = 2/21

B/18 = 4/3

Solve the second equation for B.

B = 24

Plug into the first equation to find T.

T / (24 + 18) = 2/21

T = 4

What is the solution for x in the equation 5/3 x +4=2/3 x

777dan777 [17]

Answer:

x = - 4

Step-by-step explanation:

Given

$\frac{5}{3}$ x + 4 = $\frac{2}{3}$ x

Multiply through by 3 to clear the fractions

5x + 12 = 2x ( subtract 2x from both sides )

3x + 12 = 0 ( subtract 12 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4
