Step 1
Given,
The problem is2x+13+3x15=110
Step 2
An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.
Hence it is an equation.
Least common denominator ( LCD) is the lowest common multiple of the denominators of a set of fractions.
To solve this rational equation the least common denominator is 30.
Applying LCD through out the equation.
30×2x+13+30×3x15=30×110
10(2x+1)+6(3x1)=3
20x+10+18x6=3
Combining like terms,
38x+4=3
38x=1
x=138
Thus, x=138 is solution of the given equation.
