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

Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
