Given the equation:
2/3x - 7 = 11
Determine the value of x
Solution:
In order to determine the value of x, we simply need to transpose -7 oo the other side of the equation, hence it must be taken to note, that in transposing a number, the sign changes.
⅔x - 7 = 11
⅔x = 11 + 7
⅔x = 18
Now we need to multiply both sides by 3/2 , which is the reciprocal of ⅔ in order to cancel out ⅔x and determine the value of x.
⅔x (3/2) = 18 (3/2)
x =54/2
x = 27
Final answer:
x = 27
