Answer:
x = 4.31 and y = -1.23 (to the nearest hundredth).
Step-by-step explanation:
y = 16 - 4x
3x + 4y = 8
Substitute y = 16 - 4x in the second equation:-
3x + 4(16 - 4x) = 8
3x + 64 - 16x = 8
-13x = 8 - 64 = -56
x = -56 / -1 3 = 4.308
Plugging this value into the first equation:-
y = 16 - 4(4.308)
= -1.23
Answer:
a = P - b - c
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
P = a + b + c
<u>Step 2: Solve for </u><em><u>a</u></em>
- Subtract <em>b</em> on both sides: P - b = a + c
- Subtract <em>c</em> on both sides: P - b - c = a
- Rewrite: a = P - b - c

Step-by-step explanation:
Hello!
First you have to make the denominators the same so the numbers are comparable.
You can multiply the top and bottom number in 2/3 to get 6/9
Now you add
4 6/9 + 3 1/9 = 7 7/9
The answer is 7 7/9
Hope this helps!
