Question

If 11x + 5 = 5x-7 . What is the value of x?

Answer 1

Answer:

$11x + 5 = 5 x - 7$

$= 11x - 5x = - 7 - 5$

$6x = - 12$

$x = \frac{ - 12}{6}$

$x = - 2$

$\boxed{f} \red{o} \boxed{l} \pink{l}\boxed{o} \green{w} \: \: \boxed{m} \purple{e}$

Answer 2

11x+5=5x-7

We move all terms to the left:

11x+5-(5x-7)=0

We get rid of parentheses

11x-5x+7+5=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2
