Step-by-step calculator for algebra problems.

Solving an equation:

2x+3=x+15- Adding Fractions: 1/3 + 1/4
- Multiplying Fractions: (1/3) * (3/4)

- Adding Polynomials: x^2 + x + 2 + (2x^2 - 2x)
- Multiplying Polynomials: (x+1)(x+2)
- Squaring Polynomials: (x+3)^2

- Parabola: y=2x^2+1
- Inequalities: y>3x+5; y<=x
- Line: y=2x+3

- 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

- 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

- 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
