Solve y=2-7(-3)/2-(-3)^2

$$y = \frac { 2 - 7 ( - 3 ) } { 2 - ( - 3 ) ^ { 2 } }$$

Solve for y

$$y = -\frac{23}{7} = -3\frac{2}{7} \approx -3.285714286$$

Steps for Solving Linear Equation

Multiply 7 and -3 to get -21.

$$y=\frac{2-\left(-21\right)}{2-\left(-3\right)^{2}}$$

The opposite of -21 is 21.

$$y=\frac{2+21}{2-\left(-3\right)^{2}}$$

Add 2 and 21 to get 23.

$$y=\frac{23}{2-\left(-3\right)^{2}}$$

Calculate -3 to the power of 2 and get 9.

$$y=\frac{23}{2-9}$$

Subtract 9 from 2 to get -7.

$$y=\frac{23}{-7}$$

Fraction \frac{23}{-7} can be rewritten as -\frac{23}{7} by extracting the negative sign.

$$y=-\frac{23}{7}$$

Assign y

$$y≔-\frac{23}{7}$$
