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:
5.7in
Step-by-step explanation:
using Pythagorean theorem
c^2=a^2+b^2
c=9in ,a=7in,b=xin
9^2=7^2+x^2
81=49+x^2
x^2=81-49
x^2=32
x=√32
x=5.7in(to the nearest tenth)
