How to Use the Math Equation Solver
1. Basic Equation Solver
Solves linear equations with one variable (e.g.,
x
).Format: Enter equations like
3x + 5 = 20
or2(x - 4) = 10
.Examples:
5x - 7 = 18
→ Solves forx
.x/2 + 3 = 9
→ Handles division.4(2x + 1) = 36
→ Supports parentheses.
2. Quadratic Equation Solver
Solves equations of the form
ax² + bx + c = 0
.Steps:
Enter coefficients
a
,b
, andc
.Click “Solve Quadratic.”
Examples:
x² - 5x + 6 = 0
→ Entera=1
,b=-5
,c=6
.2x² + 4x - 6 = 0
→ Entera=2
,b=4
,c=-6
.
Output: Real roots, complex roots, or double roots.
3. System of Equations Solver
Solves two linear equations with two variables (
x
andy
).Format: Enter both equations separately.
Examples:
2x + 3y = 7
andx - y = 1
→ Solves forx
andy
.y = 2x + 1
andy = -x + 4
→ Rewrite as2x - y = -1
andx + y = 4
.
Note: Equations must be in standard form (
Ax + By = C
).
Tips for Best Results
Use
*
for multiplication (e.g.,2*x
instead of2x
if unsure).For fractions, use parentheses (e.g.,
(x+1)/3 = 2
).Avoid spaces between numbers and variables (e.g.,
3x
, not3 x
).

Ensure your equations are balanced (both sides of
=
are valid).
