Answer:

[tex]\frac{2*x}{3}[/tex] + 4 = 7.

Number  = 4 .5

Step-by-step explanation:

Given  : Two-thirds a number plus 4 is 7.

To find : Expression .

Solution : We have given Two-thirds a number plus 4 is 7.

Let the number = x .

According to question :

Two-thirds a number = [tex]\frac{2*x}{3}[/tex].

Two-thirds a number plus 4 is 7.

[tex]\frac{2*x}{3}[/tex] + 4 = 7.

On subtracting 4 from both sides .

[tex]\frac{2*x}{3}[/tex] = 7 - 4 .

[tex]\frac{2*x}{3}[/tex] = 3 .

On multiplying both sides by 3 .

2x = 3 *3 .

2x = 9.

On dividing both sides by 2 .

x = 4 .5

Therefore,  [tex]\frac{2*x}{3}[/tex] + 4 = 7.

Number  = 4 .5
