Answer:
x > 4
Step-by-step explanation:
7x + 2 > 30
Subtract 2 from each side
7x + 2-2 > 30-2
7x > 28
Divide each side by 7
7x/7 > 28/7
x > 4
The fourth root? There is no simplifying to be done.
The only way to continue work on this is converting to decimal. To four places the answer is 3.3437.
If you meant to ask for the cube root, the answer is 5.
5x+y = -23
by substitution
A)
5(-3) + (-4) = -23
-15 - 4 = -23
-19 = -23
Wrong
----------------
B)
