me memory is coming back a little
Step-by-step explanation:
Simplifying
3x + 5 = 9x + - 17
Reorder the terms:
5 + 3x = 9x + - 17
Reorder the terms:
5 + 3x = - 17 + 9x
Solving
5 + 3x = - 17 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
5 + 3x + - 9x = - 17 + 9x + - 9x
Combine like terms: 3x + - 9x = - 6x
5 + - 6x = - 17 + 9x + - 9x
Combine like terms: 9x + - 9x = 0
5 + - 6x = - 17 + 0
5 + - 6x = - 17
Add '-5' to each side of the equation.
5 + - 5 + - 6x = - 17 + - 5
Combine like terms: 5 + - 5 = 0
0 + - 6x = - 17 + - 5
-6x = - 17 + - 5
Combine like terms: - 17 + - 5 = - 22
-6x = - 22
Divide each side by '-6'.
x = 3.666666667
Simplifying
x = 3.666666667

x≈ 3.7
Step-by-step explanation:
Subtract 3x from both sides and add 17 to both sides. That leaves you with 22=6x. Divide both sides by 6 to isolate the variable and you should get x equals about 3.7.
