Keep in mind that you can gather only like terms. Two terms can be summed/subtracted if they involve the same powers of the same variables.
So, going point by point:
- We can subtract the terms, because they both involve the variable
, and we have
- We can sum the terms, because they all involve the variable
, and we have
- We can't sum this terms: 3 is a pure number, while 3r involves the variable r.
- We can only sum the two terms: we have
- We can't sum this terms: -20 is a pure number, while -15p involves the variable p.
- We can sum the terms, because they all involve the variable
, and we have
The question is an illustration of a linear equation
The solution to the equation is
These are equations that have constant rates or slopes
The equation is given as:
Collect like terms in the above equation
Evaluate the like terms
Multiply both sides of the equation by 2
Hence, the value of x is 14
