Answer:

x = -2

Step-by-step explanation:

Let's find the required value of x,

→ 7 - 2x = 11

→ -2x = 11 - 7

→ -2x = 4

→ x = -4/2

→ [ x = -2 ]

Therefore, the value of x is -2.

Solve (get the variable by itself): m / (-4) = -2.95
kenny6666 [7]
M / -4 = -2.95
As you can see, the variable m is currently in a fraction with a denominator of -4. So to get ride of the fraction and find m and its value, you should multiply both sides by the denominator of the fraction, which is in our case -4.
So m / -4 = -2.95
(m/-4) * -4 = -2.95 * -4
m = 11.8

You can recheck your answer (very important):
m / -4 = 11.8 / -4 = -2.95
The answer has been approved.

Hope this Helps! :)
