Answer:
The solution is (2, 4)
Step-by-step explanation:
Note that if we multiply the second equation by -2, the first term of this revised equation will be -14x, which will cancel out the +14x in the first equation:
14x - 8y = -4 => 14x - 8y = -4
-2(7x + 3y = 26) => -14x - 6y = -52
----------------------
-14y = -56, or y = 4
Substituting 4 for y in the first equation, we get 14x - 8(4) = -4, or
14x = 28 => x = 2
The solution is (2, 4)

Answer:
See below
Step-by-step explanation:
Tariku in second grade read 6 books each month during the year. This is equal to 6(12) = 72.
Tariku in third grade read 8 books each month during the year. This is equal to 8(12) = 96.
You can find the total amount with any of the below equations:
- 6(12) + 8(12)
- 12(6+8)
- 12(14)
For a total number of months x the equations would be the same except with x instead of 12.
