Answer:
Step-by-step explanation:
The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.Understand what multi-variable equations are. Two or more linear equations that are grouped together are called a system. That means that a system of linear equations is when two or more linear equations are being solved at the same time.[1] For example:
8x - 3y = -3
5x - 2y = -1
These are two linear equations that you must solve at the same time, meaning you must use both equations to solve both equations.
The answer is choice A- 68
Add 4.9 to each side so 4r>19.85 and divide both side by 4. So r> 4.96 so say any point over 5 and you are correct

Step-by-step explanation:
Answer: 5 green buckets and 3 white buckets
Step-by-step explanation: each green bucket is 7 liters so if Austin buys 5 of them that'll equal 35 liters already. And each white bucket is 1 liter so if he buys 3 of those that'll get him to 38
