Pre-algebra concepts, geometry, and statistical thinking for seventh grade students.
As you advance, you'll learn to perform operations on more complicated expressions and solve linear equations that require more than one step.
When simplifying expressions, group together terms that have the same variable and exponent. For example, \(2x + 3x = 5x\).
The distributive property allows you to multiply a number across terms in parentheses: \(a(b + c) = ab + ac\).
Sometimes, you'll need to use several operations to solve for the variable, like \(2(x + 3) = 12\).
\(a(b + c) = ab + ac\)
These skills help you break down and solve more challenging problems, from algebra puzzles to science formulas.
Simplifying \(4x + 2x - 3 = 9\) to solve for \(x\).
Applying \(2(x + 5) = 16\) to find the value of \(x\).
Operations with expressions and multi-step equations help us solve more advanced and realistic math problems.
