Simplifying

3x + 2y = 35

Solving

3x + 2y = 35

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3x + 2y + -2y = 35 + -2y

Combine like terms: 2y + -2y = 0

3x + 0 = 35 + -2y

3x = 35 + -2y

Divide each side by '3'.

x = 11.66666667 + -0.6666666667y

Simplifying

x = 11.66666667 + -0.6666666667y

$x^\frac{4}{3} x^ \frac{2}{3}$ Lets get started :)

Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.

When multiplication occurs in the same base, we add the powers
$x^\frac{4}{3} x^ \frac{2}{3}$
↓ (I am going to perform the problem separately and then give the final answer as the power to x)
$\frac{4}{3} + \frac{2}{3}$ = $\frac{6}{3} = 2$
↓
x²

$(x^2)^ \frac{1}{3}$

The power of a power should be performed by multiplying the powers together.
2 x $\frac{1}{3}$ = $\frac{2}{3}$

$x^\frac{2}{3}$

Your final answer will be the second option
