You can subtract the 2x to make it -y=-2x-2 and add the x to make it -2y=x+4. for elimination method multiply the equation (-2)-y=-2x-2. Hope this helps. You can also do substitution method
Answer:
2x = 70
Step-by-step explanation:
4x - 2x = 70
2x = 70
x = 70/2
x = 35
Answer: A, 4^4
Step-by-step explanation:
4^7/4^3 = 4^4
Answer:
1, -6 and -5
Explanation:
To solve the equation means to get the values of n which satisfy the given equation.
The equation given is:
(n-1) (n+6) (n+5) = 0
This equation will be true if any of the terms (brackets) is equal to zero.
This means that:
either n-1 = 0 .............> n = 1
or n + 6 = 0 ................> n = -6
or n + 5 = 0 ................> n = -5
Hope this helps :)
