What's the answer to 4x+7=10x-11?
I've tried it like 10 times and i don't seem to be getting the right answer! Please Help!

Subtract 7 from both sides:
4x = 10x - 18
Subtract 10x from both sides:
-6x = -18
Divide by -6:
x = 18/6 = 3
Another way to solve this would be by using graphs; graphing y = 4x + 7 and y = 10x - 11 in the same plane would allow you to find where the lines cross, thus giving you the answer. Seems a bit redundant for this, though.
4x = 10x - 18
Subtract 10x from both sides:
-6x = -18
Divide by -6:
x = 18/6 = 3

4x + 7 = 10x - 11
18 = 6x
3 = x
18 = 6x
3 = x
-
4x - 10x = -11 - 7
→ -6x = -18
→ x = 3
→ -6x = -18
→ x = 3

18 = 6x
x = 3
x = 3

Answer x=3
-
4x-10x =-6x
-11-7= -18
-6x=18
x=3
-11-7= -18
-6x=18
x=3
-
4x-10x
=-6x
-11-7
= -18
-6x
=18
x=3
=-6x
-11-7
= -18
-6x
=18
x=3
