Linear equations are:
Non-linear equations are:
Step-by-step explanation:
Lets define linear and non-linear first.
Linear equation is that equation whose degree is one. Degree is the highest power of a variable in an expression or equation.
Similarly, an equation with degree greater than 2 are called non-linear equation
In the given equations,
=> Degree: 3
=> Degree: 1
=> Degree: 2
=> Degree:1
=> Degree:2
Hence,
Linear equations are:
Non-linear equations are:

At first, weIf assumed that the two expressions are equal and then we can write the following and solve for x
5(3x-6)=15x-30
Then perform transposition method such as shown below
15x-30=15x-30
15x-15x=-30+30
0=0
They are equal since the derived values on both sides is the same which is zero.
First we need to know how many miles per hour they drove the first time. This would be found by division. 168/3.5=48
Then we need to add 5 miles per hour for the average.48+5= 53
Next we need to multiply 2 1/4 by the new miles per hour 53*2.25=119.25
After that we need to know how many miles they drove 119.25+168=287.25 miles.
Finally to get an improper fraction we need to change 287.25 miles to it.
We already have 1/4 for .25 so we multiply 287 by 4 and add it to the 1/4 we already have and it makes it out to be 1149/4
Hope this helps!
