Please be specific about the kind of help you want. Ideally you'd do all the work you can and then stop and ask questions whose answers might help you move forward again. Graph the function f(x)=2x+4. This is the equation of a straight line with slope 2 and y-intercept 4. What help do you need in doing this? What help do you need beyond this?
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
