Two thirds of a number reduced by 11 is equal to 4 more than the number. Find the number.

Answer:
b
Step-by-step explanation:
Let x be that number
The equation will be the following:
● (2/3)x - 11 = x + 4
Add 11 to both sides
● (2/3)x - 11 + 11 = x + 4 + 11
● (2/3)x = x + 15
Add -x to both sides
● (2/3)x - x = x + 15 - x
● 2x -3x/3 = 15
● -x/3 = 15
Multiply both sides by -3
● -x/3 × 3 = 15 × -3
● x = -45
