The final answer is (2,1).
Step 1: Solve for either x or y in one of the two equations.
x + 3y = 5
- 3y - 3y
----------------------
x = -3y + 5
Step 2: Substitute the expression you got for x into the opposite equation.
-3y + 5 - 3y = -1
-6y + 5 = -1
- 5 - 5
--------------------
-6y = -6
------ -----
-6 6
y = 1
Step 3: Plug in the solution you got for y into either of the 2 equations.
x + 3(1) = 5
x + 3 = 5
- 3 - 3
---------------
x = 2
1 pt= 437.1765 mL
0.5 pt= 0.5x437.1765= 218.58825 mL
Ratio = 218.58825/750= 0.2915 % =29.15%
Number of shares
1050/10=105
After one year share value
10×(1+0.13)=11.3
After the second year share value
11.3×(1−0.05)=10.735
Total
10.735×105=1,127.175
Answer:
x = y(z + 3r)
Step-by-step explanation:
Given
z = - 3r ( add 3r to both sides )
z + 3r = ( multiply both sides by y )
y(z + 3r) = x
