$2 y - y + 7 - 1 + 3 + 7 x^{2} - 4 y$

Step 1

Subtract $y$ from $2 y$ .

$y + 7 - 1 + 3 + 7 x^{2} - 4 y$

Step 2

Subtract $4 y$ from $y$ .

$- 3 y + 7 - 1 + 3 + 7 x^{2}$

Step 3

Step 3.1

Subtract $1$ from $7$ .

$- 3 y + 6 + 3 + 7 x^{2}$

Step 3.2

Add $6$ and $3$ .

$- 3 y + 9 + 7 x^{2}$

Step 3.3

Move $9$ .

$- 3 y + 7 x^{2} + 9$

Step 3.4

Reorder $- 3 y$ and $7 x^{2}$ .

$7 x^{2} - 3 y + 9$

$7 x^{2} - 3 y + 9$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
