Question

Find x if x is not -6, and 9/12 = 5/(6+x)

Answer 1

9/12=5/(6+x)
9(6+ x) =5*12
54+ 9 x =60
9x = 60- 54

9 x =6
x = 6/9
=2/3
= 0.666
...............

Answer 2

The value of x will be 0.67

Linear equation

• Linear equation is an equation between two variables that gives a straight line when plotted on a graph.
• A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

How to solve this problem?

The steps are as follow:

• The given equation is as follow:

$\frac{9}{12}=\frac{5}{(6+x)} \\ 9(6+x)=60\\54+9x=60\\9x=60-54\\9x=6\\x=\frac{6}{9} \\x=0.67$

So the value of x will be 0.67
