2. When is it best to solve a system of equations using substitution?
3. When it is best to solve a system of equations using elimination? When it is
Plz answer all questions

1 If the equations do not involve fractions or decimals, and you have a good visual understanding of linear equations, graphing on the coordinate plane is a good option.

2 Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method.

3 Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
