1. 5x-y=4
2. -4/3+1/3y-2/3z
3. x=5+1/2y -3/2z
And/or the answer to the whole thing could be that the statement is incorrect.
Answer:
B. (2, 3)
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using graphing
Step-by-step explanation:
<u>Step 1: Define system</u>
y = x + 1
y = -1/2x + 4
<u>Step 2: Identify Solution</u>
The solution to the systems of equations when graphed will be where the 2 lines intersect. According to the graph, the 2 lines intersect at (2, 3).
1. - We need to add fractions
4 6/8 + 3 2/3 = 8 1/2
2. Adding fractions.
8 1/2 + 4 2/4 = 13
3. Once again, adding fractions.
2 4/6 + 5 1/2 = 8 1/6
Those are the answers to 1, 2 and 3!
Please know that these were from my mind, so they may be wrong.
Although, I did my best, and I think they are all right.
Glad I could help, and good luck!
