To solve the equation, divide both sides by 5. The solution is c = 4.
A linear equation is an equation of which the highest degree of its variables is 1.
Steps to solve linear equations:
- Simplify the expressions. If there are parentheses, remove them by multiplying the corresponding terms.
- Combine the same terms.
- Isolate the variable on one side by using subtraction or addition.
- Use division or multiplication to find the value of the variable.
- Recall that if we subtract or add the same number to both sides of an equation, it does not change the equality.
The given problem:
Solve 5c = 20
Notice that the variable, c, is already isolated on the left side.
Divide both sides by 5:
5c : 5 = 20 : 5
c = 4 (solved)
