Question

Pls ayuda tengo una pregunta de matematica dice así:
28-2x<20

Answer 1

Respuesta:

Simplifying

28 + -2x = 20

Solving

28 + -2x = 20

Solving for variable 'x'.

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

Add '-28' to each side of the equation.

28 + -28 + -2x = 20 + -28

Combine like terms: 28 + -28 = 0

0 + -2x = 20 + -28

-2x = 20 + -28

Combine like terms: 20 + -28 = -8

-2x = -8

Divide each side by '-2'.

x = 4

Simplifying

x = 4
