How to Subtract Two Equations

What is the process of subtracting two equations?

Given the following data:

  • Equation 1 = 7x - 9
  • Equation 2 = 2x^2 - 11

Answer:

To subtract two equations, in this case equation 1 from equation 2, follow these steps:

Calculate the subtraction as shown below:

In this exercise, you're required to subtract equation one (7x - 9) from equation two (2x^2 - 11). This means you will subtract one equation from the other to produce a new equation.

Mathematically, the expression is as follows:

2x^2 - 11 - (7x - 9)

Opening the bracket, you get:

2x^2 - 11 - 7x + 9

2x^2 - 7x - 11 + 9

2x^2 - 7x - 2

Note: The resulting equation is a quadratic equation.
