Answer:
The number is 13 /24
Step-by-step explanation:
Let the number = x
x - (- 11/12) = 3x - 1/6
x + 11/12 = 3x - 1/6
Collect like terms ;
x - 3x = - 1/6 - 11/12
-2x = (-2 - 11) / 12
-2x = - 13 / 12
-2x(12) = - 13
-24x = - 13
x = 13 / 24
D:) infinitely many solutions
Answer:
x=3
Step-by-step explanation:
In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?
<em>In order to find out, you need to get X by itself. </em>
The first step is to subtract 115 from both sides.
7x+115=136
-115 | -115
7x=21
Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.
7x=21
/7 | /7
x=3
This is because you have 7 X's and you need to have only 1 of the X's.
