Enter the coefficients of x and y of two separate equations into the calculator. The linear combination calculator will solve for both x and y.

## Linear Combination Formula

The following formula can be used to calculate the x and y values of two equations using linear combination.

ax + by = c

dx + ey = f

x =( c – by )/ a = (f -ey)/d

y = (f-dx)/e = (c-ax)/b

- Where x and y are the coordinate points
- a and b are coefficients in one equation
- d and e are coefficients in the other equation
- f and c are constants

## Linear Combination Definition

A linear combination is the relationship between two equation in the formula ax + by = c. The two equations allow you to solve for missing values of x and y if a, b, and c, are known.

## Linear Combination Example

How to calculate a linear combination?

**First, determine the values of a.**Find the value of a in both equations.

**Next, determine the value of b.**Find the value of b in both equations

**Next, determine the value of c.**Find the value of c in both equations.

**Finally, calculate x and y.**Using the formulas for linear combination above, calculate x and y.

## FAQ

**What is linear combination?**

A linear combination is a mathematical process that involves two related equations. These equations are both in the form ax + by = c. Knowing the values of a, b, and c from both equations one can calculate the missing values of x and y that would solve those equations.

**What are x and y coefficients?**

The x and y coefficients are values that represent the change in true x and y values with respect to the equation or line the equation represents.

**What is a slope?**

A slope is the measure of vertical increase over the rise in horizontal increase of a line.
