Question

calculate
5x-4x^2+3 when x+2

Answer 1

Step-by-step explanation:

x+4=5x+2

Simplifying

x + 4 = 5x + 2

Reorder the terms:

4 + x = 5x + 2

Reorder the terms:

4 + x = 2 + 5x

Solving

4 + x = 2 + 5x

Solving for variable 'x'.

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

Add '-5x' to each side of the equation.

4 + x + -5x = 2 + 5x + -5x

Combine like terms: x + -5x = -4x

4 + -4x = 2 + 5x + -5x

Combine like terms: 5x + -5x = 0

4 + -4x = 2 + 0

4 + -4x = 2

Add '-4' to each side of the equation.

4 + -4 + -4x = 2 + -4

Combine like terms: 4 + -4 = 0

0 + -4x = 2 + -4

-4x = 2 + -4

Combine like terms: 2 + -4 = -2

-4x = -2

Divide each side by '-4'.

x = 0.5

Simplifying

x = 0.5
