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

Solve equation. Show steps <br> 8+x=4x+2
statuscvo [17]

Answer:

x=2

Step-by-step explanation:

8 + x = 4x +2

Subtract 4x from both sides:

8 + x - 4x = 4x + 2 - 4x

Group like terms:

x - 4x + 8 = 4x + 2 -4x

Simplify the arithmetic:

-3x + 8 = 4x + 2 -4x

Group like terms:

-3 + 8 = 4x - 4x + 2

Simplify the arithmetic:

-3x + 8 = 2
