Solve y=2(-3)^3-(-3)^2+8(-3)-3

$$y = 2 ( - 3 ) ^ { 3 } - ( - 3 ) ^ { 2 } + 8 ( - 3 ) - 3$$

Solve for y

$$y=-90$$

Steps for Solving Linear Equation

Calculate -3 to the power of 3 and get -27.

$$y=2\left(-27\right)-\left(-3\right)^{2}+8\left(-3\right)-3$$

Multiply 2 and -27 to get -54.

$$y=-54-\left(-3\right)^{2}+8\left(-3\right)-3$$

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

$$y=-54-9+8\left(-3\right)-3$$

Subtract 9 from -54 to get -63.

$$y=-63+8\left(-3\right)-3$$

Multiply 8 and -3 to get -24.

$$y=-63-24-3$$

Subtract 24 from -63 to get -87.

$$y=-87-3$$

Subtract 3 from -87 to get -90.

$$y=-90$$

Assign y

$$y≔-90$$
