Answer:
Look below
Step-by-step explanation:
1) x = 14, because 14 * 14 = 196
2) x = 3 / 16, because ( 3 / 16 ) * ( 3 / 16 ) = 9 / 256
3) x = 8, because 8 * 8 * 8 = 512
4) x = 4 / 7, because ( 4 / 7 ) * ( 4 / 7 ) * ( 4 / 7 ) = 64 / 343
1. Isolate the variable
Ex. 3n=12 Divide 3 on both sides. You get n=4
2. Inequality
Ex. 3x>x+7
3. Distributive Property
-10(x+5)=40
-10x-50=40
