Ответ:
x = 3
Step-by-step explanation: First, isolate the x term by adding 4 to
both sides of the equation. We get 2/3x = 2.
Next, multiply both sides of the equation by the
reciprocal of 2/3 which is 3/2 to get x by itself.
So we have (3/2) 2/3x = 2 (3/2).
On the left, (3/2) 2/3 cancels and we have x.
On the right, the 2's cancel and we have 3.
So x = 3 is our answer.
