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).
