Easy. Okay. We are trying to find out how much of the pizza they both ate together. To do this we need a common denominator. A common denominator of 3/4 and 1/8 are 8. We don't need to convert 1/8 because it already has 8 as the denominator. So we convert 3/4 into a fraction that has a fraction with a denominator of 8. We multiply both the numerator and denominator by 2 which means 3/4 is equal to 6/8. Now all we have to do is 6/8 + 1/8 which we get 7/8. So the answer is 7/8. I hope this helps.

Discussion for Applications of Linear Systems

Lostsunrise [7]

Step-by-step explanation:

There are certain methods for solving a system of equations. Some of which are:

Substitution Method
Elimination Method
Graphing Method

Substitution Method

Substitution method to solve a system of equations is suitable if a variable of a any equation seems isolated or could comfortably be isolated without any ration/fraction resulting.

For example, for the following system of equations

x - 2y = 11....[A]

x = 5 - y....[B]

substituting the value of x = 5 - y from equation [B] into equation [A], so that

(5 - y) - 2y = 11

5 - y - 2y = 11

3y = -6

y = -2

Elimination Method

Elimination method to solve a system of equations is suitable if both equation are in standard form, and just adding or subtracting the equations to determine an equation in one variable.

For example, for the following system of equations

2x + 7y = -5....[C]

5x - 7y = 12....[D]

Adding Equation [C] and Equation [D].

7x + 0 = 7

x = 1

Graphing Method

Sometimes graphing method may be used to solve the system of the equation and visualize the solution.

For example,

y = -2....[E]

y = 3x + 1....[F]

The solution for this system of equation is the point of intersection of both the lines, which is shown in attached figure. The point of intersection is (-1, -2).

Hence, the solution of this system of equations is (-1, -2), as shown in attached figure.

Keywords: system of equations, elimination method, substitution method, graphing method
