Answer:
Elimination
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
Answer:
x=14
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−9)=20
Step 1: Simplify both sides of the equation.
4(x−9)=20
(4)(x)+(4)(−9)=20(Distribute)
4x+−36=20
4x−36=20
Step 2: Add 36 to both sides.
4x−36+36=20+36
4x=56
Step 3: Divide both sides by 4.
4x
4
=
56

x=14
Let the Total Number of dogs Larry has be : D
Let the Total Number of cats Larry has be : C
Given : Larry sold 5 dogs
Remaining Number of dogs Larry has : D - 5
Given : Larry sold 4 cats
Remaining Number of cats Larry has : C - 4
Given : After selling 5 dogs and 4 cats, Larry still has more dogs than cats
D - 5 > C - 4
