Answer:
x = -14
Step-by-step explanation:
4x + 8 = 3x - 6
4x = 3x - 14
x = -14
You can answer this problem in two different ways: the first being (17 - 5) * x, and the second being 12 * x.
Answer:
0.2794
Step-by-step explanation:
11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
