No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate x, then solve for y.
The only possible answers are 94 or 14. (100-30)/5= 70/5=14. 100-(30/5)= 100-6=94. These are the only two possible answers.
Answer:
- 39
Step-by-step explanation:
x + 7= (-2)^5
x + 7 = -32
x = - 32- 7
x = - 39
Answer: C
Step-by-step explanation:
Answer:
2 - 9
3 - 16
4 - 25.
Step-by-step explanation:
I think you want this:
2 - (2+1)(2+1)
3 - (3 + 1)(3+1)
4 - (4+1)(4 + 1)
You substitute 2, 3 and 4 into x - (x+1)(x+1) and work them out.
