Answer:
The answer is 9
Step-by-step explanation:
3 times 6 is 18 so 2x+18=36 then 36-18 is 18 and 18 divided by 2 is 9
Factors of 26: <u>1</u>, <u>2,</u> 13, 26 (1 × 26, 2 × 13)
Factors of 42: <u>1</u>, <u>2</u>, 3, 6, 7, 14, 21, 42 (1 × 42, 2 × 21, 3 × 14, 6 × 7)
The greatest common factor they have is 2
Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
