USING AN EQUATION
Sometimes you are given a word problem that needs an equation to be solved. You have to set up that equation before you can solve it.
Follow the steps to learn how to do this.
1. Read the problem.
2. Decide what operation is needed.
a. addition-add, total, all together, sum, etc.
b. subtraction-less, subtract, minus, difference, etc.
c. multiplication-times, product, of, etc.
d. division-quotient, into, divided by, etc.
3. Remember that is means equals.
4. Set up the equation going word to word throughout the problem.
5. Solve the equation.
The sum of a number and ten is eight.
x + 10 = 8
- 10 -10
x = -2
The quotient of some number and negative six is five.
x/-6 = 5
x = -30
A number less ten is less than seven.
x - 10 < 7
+ 10 +10
x < 17
