## Why can you equate coefficients?

In mathematics, the method of equating the coefficients is a way of solving a functional equation of two expressions such as polynomials for a number of unknown parameters. It relies on the fact that two expressions are identical precisely when corresponding coefficients are equal for each different type of term.

## How do you equate an equation?

Since both equations are in the form y = f(x) we can equate the right hand sides of the equations and solve for x. 2x +2 = −x + 5 3x = 3 x = 1. We can now substitute x = 1 into either equation to find y: y = 2(1) + 2 = 4.

## How do you equate a linear equation?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, its pretty easy to find both intercepts (x and y).
