Answer:
option 4
Step-by-step explanation:
3x - 4y = 18 ⇒ 3x - 4y = 18
2x + y = 1 ⇒ 8x + 4y = 4
11x = 22
11 11
x = 2
2x + y = 1
2(2) + y = 1
4 + y = 1
- 4 - 4
y = -3
(x, y) = (2, 3)
Answer:
Step-by-step explanation:
The integers are -8 and -6.
To find these, first assume that the first integer is x. Then, because it is an even integer, assume the next is x + 2. Now we can write an equation to solve.
Tripling the greater = subtracting 10 from the lesser
3(x + 2) = x - 10 ----> Distribute the 3
3x + 6 = x - 10 ----> Subtract x from both sides
2x + 6 = -10 ----> Subtract 6 from both sides
2x = -16 ----> Divide both sides by 2
x = -8
Which is the first integer. We then can determine that the second one, which is two higher than the first, would be -6.
