Solve x=-3(-5^3)+4(-5^2)-(-5)+8

$$x = -3(- { 5 }^{ 3 } )+4( { -5 }^{ 2 } )-(-5)+8$$

Solve for x

$$x=488$$

Steps for Solving Linear Equation

Calculate 5 to the power of 3 and get 125.

$$x=-3\left(-125\right)+4\left(-5\right)^{2}-\left(-5\right)+8$$

Multiply -3 and -125 to get 375.

$$x=375+4\left(-5\right)^{2}-\left(-5\right)+8$$

Calculate -5 to the power of 2 and get 25.

$$x=375+4\times 25-\left(-5\right)+8$$

Multiply 4 and 25 to get 100.

$$x=375+100-\left(-5\right)+8$$

Add 375 and 100 to get 475.

$$x=475-\left(-5\right)+8$$

The opposite of -5 is 5.

$$x=475+5+8$$

Add 475 and 5 to get 480.

$$x=480+8$$

Add 480 and 8 to get 488.

$$x=488$$

Assign x

$$x≔488$$
