Solution to the system of linear equations is (5/3, -14/3)
Step-by-step explanation:
- Step 1: The system of linear equations are
8x + 2y = 4 ------ (1)
16x - y = 18 ------ (2)
- Step 2: Multiply eq(2) by 2 to make coefficients of y equal
8x + 2y = 4
16x - 2y = 36
- Step 3: Add the two equations
⇒ 24x = 40
⇒ x = 40/24 = 5/3
- Step 4: Find the value of y
⇒ 8 × 5/3 + 2y = 4
⇒ 40/3 + 2y = 4
⇒ 2y = 4 - 40/3 = -28/3
⇒ y = -14/3
Answer:
The solution would be C, 28/9
the spread of the middle data is called the interquartile range and the left and right twenty five percent data are both called the twenty five percent quartiles

The answer is option (c) 7xy^2-2xy^2
Hello!
You solve this algebraically
4(m + 9) = -2(m - 5) + 2
Distribute the 4
4m + 36 = -2(m - 5) + 2
Distribute the -2
4m + 36 = -2m + 10 + 2
combine like terms
4m + 36 = -2m + 12
Add 2m to both sides
6m + 36 = 12
Subtract 36 from both sides
6m = -24
Divide both sides by 6
m = -4
Hope this helps!
