💡To solve equations, perform the opposite operation of addition or subtraction.
🔑Isolate the variable by getting rid of any constants or coefficients.
📚Cross multiplication can be used to solve equations with fractions.
✖️Multiplication and division are inverse operations that can solve equations.
🌀Simplify equations by combining like terms before solving.
How do I solve equations with fractions?
—Use cross multiplication to eliminate the denominators and solve the resulting equation.
What is the first step in solving an equation?
—Isolate the variable by getting rid of any constants or coefficients using inverse operations.
How do I solve equations with variables on both sides?
—Combine like terms and then isolate the variable using inverse operations.
Why is it important to simplify equations before solving?
—Simplifying equations helps to identify like terms and makes the equation easier to solve.
Can equations have multiple solutions?
—Yes, some equations can have infinite solutions or no solutions at all.
00:00This video discusses how to solve basic equations.
00:02An example equation is given: x + 4 = 9.
00:08To find the value of x, subtract 4 from both sides.
00:14The solution is x = 5 after simplifying the equation.
00:22Another example equation is given: x + 7 = 11.
00:26Subtract 7 from both sides to find x = 4 as the solution.
00:35A third example equation is given: x - 5 = 6.
00:42Add 5 to both sides to get x = 11 as the solution.
