The right answer is probably C
Answer:
n - 6 < -4
Step-by-step explanation:
6 being less than n hints at a subtraction equation, n coming first as the value of the constant is currently unknown. 'Less than -4' hints that -4 is the value on the other side of the inequality, < acting as the 'equal' sign in this sense.
The solution is x = 4 and y = -1
Step-by-step explanation:
The system of equation is:
- y =
x - 3 - y = x - 5
To solve it using the elimination method do that
∵ y = x - 3 ⇒ (1)
∵ y = x - 5 ⇒ (2)
- Subtract equation (1) from equation (2) to eliminate y
∵ y - y = (x - x) - 5 - (-3)
- Remember (-)(-) = (+)
∴ 0 = x - 5 + 3
∴ 0 = x - 2
- Add 2 to both sides
∴ 2 = x
- Multiply both sides by 2
∴ 4 = x
∴ x = 4
- Substitute the value of x in equation (1) or (2) to find y
∵ y = 4 - 5
∴ y = -1
The solution is x = 4 and y = -1

Answer:
x is 30/7
Step-by-step explanation:
You want to isolate x.
First, solve 5 * 6/7. The answer is 30/7.
Next, divide both sides by 6/7. This will cancel out the 6/7 on the left . For the right, when dividing fractions, you must take the reciprocal of the second fraction and multiply by it. So instead of having 30/7 divided by 6/7, you will have 30/7 * 7/6. The answer is 210/45 which simplifies to 5.
Third, you want to divide both sides by 7/6. Again the 7/6 on the left will be cancelled out. And you must do 5 * 6/7. In order to make the 5 look like a fraction to reduce confusion, you can set it over 1 (thus, you would do 5/1 * 6/7). The answer is 30/7.
You can plug it back into the equation to check.
