The equation the quantity of x plus 20 over 2 = 3x represents when two tutoring services with different rate plans charge the sa
victus00 [196]

The solution to the equation is x = 4

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the solution to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the equation is given as

(x + 20)/2 = 3x

Multiply both sides of the equation by 2

x + 20 = 6x

Subtract x from both sides of the equation

5x = 20

Divide both sides of the equation by 5

x = 4

hence, the solution to the equation is x = 4

How to solve -4x+8y=-24
lukranit [14]

Answer:

x=6

y=-3

Step-by-step explanation:

<em><u>solve for x-</u></em>

-4x+8y=-24 replace y with 0

-4x+8(0)=-24

-4x=-24 divide by -4 on both sides

x=6

<u><em>Solve for y-</em></u>

-4x+8y=-24 replace x with 0

-4(0)+8y=-24

8y=-24 divide by 8 from both sides

y=-3
