☀ Numeric expressions apply operations to numbersor example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example2(x + 8y) is an algebraic expression.
- Evaluate x^2+2x for x=5: x^2+2x @ x=5
- Evaluate 2x^2+2y for x=5, y=3: 2x^2+2y @ x=5, y=3
Solving Equations
- Solve x+5=8: x+5=8
- Solve system x+y=7 and x+2y=11: x+y=7; x+2y=11
- Check answer (3,4) for equations x+y=7 and x+2y=11: x+y=7; x+2y=11 @ x=3,y=4
Solving Inequalities
- Solve 2x+3>23: 2x+3>23
- Solve x>2 and x+3<7: x>2\ and\ x+3<7
- Solve |2x+3|>=23: |2x+3|>=23
