Respuesta :
x = 25
-4 * 25 = -100 + 88 = -12
since adding a negative number to a positive one is the same as subtracting both positives this is correct
-4 * 25 = -100 + 88 = -12
since adding a negative number to a positive one is the same as subtracting both positives this is correct
Here, we are basically solving for x to find it's value:
Subtract 88 from both sides:
[tex]-4x + 88-88 = -12-88 [/tex]
Now we have:
[tex]-4x=-100 [/tex]
divide both sides by -4
x=25
Final answer x=25
To check:
Plug in 25 for x:
-4(25) + 88 = -12
-12=-12 TRUE.
Subtract 88 from both sides:
[tex]-4x + 88-88 = -12-88 [/tex]
Now we have:
[tex]-4x=-100 [/tex]
divide both sides by -4
x=25
Final answer x=25
To check:
Plug in 25 for x:
-4(25) + 88 = -12
-12=-12 TRUE.
