Question

7x+9=5x-9
procedimiento ​

Answer 1

Respuesta:

Simplifying 7x + -9 = 5x + 9 Reorder the terms: -9 + 7x = 5x + 9 Reorder the terms: -9 + 7x = 9 + 5x Solving -9 + 7x = 9 + 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. -9 + 7x + -5x = 9 + 5x + -5x Combine like terms: 7x + -5x = 2x -9 + 2x = 9 + 5x + -5x Combine like terms: 5x + -5x = 0 -9 + 2x = 9 + 0 -9 + 2x = 9 Add '9' to each side of the equation. -9 + 9 + 2x = 9 + 9 Combine like terms: -9 + 9 = 0 0 + 2x = 9 + 9 2x = 9 + 9 Combine like terms: 9 + 9 = 18 2x = 18 Divide each side by '2'. x = 9 Simplifying x = 9

Answer 2

Respuesta:

-9

Explicación paso a paso:

7x + 9 = 5x - 9 el 5x pasa al otro lado con

7x - 5x + 9 = - 9 signo cambiado

2x= - 9 - 9. El 9 se va al otro lado

X = - 18/2. El 2 pasa a dividir

X = - 9
