Set up the equation and solve:

8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation)

6x = 30 (divide both sides of the equation by 6)

x = 5

Q: What does x equals if the sum is 8x plus 8 equals 2x plus 38?

x2 + 2x - 38 = 0 ∴ x2 + 2x + 1 = 39 ∴ (x + 1)2 = 39 ∴ x + 1 = ±√39 ∴ x = -1 ±√39

2x + 21 = 97 2x = 76 x = 38 Check it. 5 x 38 + 21- 3 x 38 190 + 21 - 114 211 - 114 = 97 It checks.

30 plus 30 equals 60 and 60 minus 38 equals 22

2x^2=76, x^2=38, x=square root of 38- about 6.17

8x + 38 = 2x + 2 The first thing you want to do is get all the variables on one side and all the stand-alone numbers on the other side. To do this, you just do the opposite of what the sign is (Ex: Since it is "plus 38" on the left side, to get it to the right we subtract 38) 8x = 2x + 2 -38 Now you can simplify the right side: 8x = 2x -36 And then you want to get the variables on the left side of the problem. So since 2x is positive, you want to subtract 2x from both sides of the equation. 8x - 2x = -36 Simplify the left side: 6x = 36 And then from there you can divide both sides by 6. x = 6
