Two linear equations in the form ax + by = c. Type coefficients, see both lines plotted, and find the intersection (which is the solution). The substitution / elimination method is shown step by step.
Equation 1 (blue)
x +
y =
Equation 2 (green)
x +
y =
Solution
x = 3, y = 2
The two lines cross at (3, 2). This satisfies both equations.
