(3x + 4)³ = 2197

Taking the cube root in this case is easier, although we can do it the extended way which is complicated.

\sqrt[3]{(3x+4)^3} = \sqrt[3]{2197}
3x + 4 = 13

Now solve normally.

subtract 4
3x + 4 = 13
       -4    -4

3x = 9
Divide by 3 to isolate 3

\frac{3x}{3}  =  \frac{9}{3}
3 and 3 cancels out

x = 3

(3x+4)³=2197

3x+4=z

z³=2197
z=∛2197
z=13

Then:
3x+4=13
3x=13-4
3x=9
x=9/3
x=3

answer: x=3

Solve by elimination:<br> x + 9y = 8<br> -6X - 9y = -3
WITCHER [35]

Answer:

(-1,1)

Step-by-step explanation:

x + 9y = 8

-6x - 9y = -3

Add the two equations together to eliminate y

x + 9y = 8

-6x - 9y = -3

---------------------

-5x   = 5

Divide by -5

-5x/-5 = 5/-5

x = -1

Now solve for y by substituting into the first equation

x+9y = 8

-1 + 9y =8

Add 1 to each side

-1+1 + 9y = 8+1

9y=9

Divide each side by 9

9y/9 = 9/9

y = 1
