The student will solve multi-step linear equations in one variable with the variable on one or both sides of the equation, including practical problems that require the solution of a multi-step linear equation in one variable.
Can include these types of equations:
2π₯+1 = βπ₯4
β3(2π₯+7)= 12π₯
2π₯+7β5π₯=27
β5π₯β(π₯+3)= β12
An expression represents several terms that have a certain quantity. An equation is a math sentence which states that two expressions are equal.
Like terms have the same variable parts & exponents.
7x and -8x --> you can combine them
7x and -8xy --> you cannot combine them (different variables)
7x and -8x^2 --> you cannot combine them (different exponents)
Represent and solve multi-step linear equations with the variable on one/both sides of the equation (up to four steps) using concrete materials and/or pictorial representations.
Apply properties to solve multi-step equations (up to four steps). Equations may contain the distributive property or require combining like terms.
Write verbal expressions and sentences as algebraic expressions and equations (and vice versa).
Solve practical problems that require using a multi-step equation.
Confirm (check) algebraic solutions to equations.
When checking your answer:
Enter the value for the variable.
Type in each side of the equation exactly how you see it.
They should come out to be equal.
