situation creation
The empty cup weighs 100g and the water weighs x grams.
100+x=250
Explore new knowledge
Look at the equation in the diagram to find the value of x.
Solution: x+58=79
x+58-58=79-58...subtract 58 from both sides of the equation at the same time
x=21
The value of the unknown that makes the left and right sides of the equation equal is called the solution of the equation.
The process of finding the solution to an equation is called solving the equation.
give it a try
Solving equations.
x-27=56 x÷9=80
practice
1. Find the solution to the equation in the brackets and put a “√” on it.
2. Look at the equations in the diagram and solve them.
Solution: 39+x=98
39+x-39=98-39
x=59
