Question

Two-thirds a number plus 4 is 7

Answer 1

The equation (form) is:
`(2)/(3)x + 4 = 7`

The solution of the equation is:
`x = (9)/(2)`

Step-by-step explanation:

First, let's call the number we are going to solve for "x".

Then two thirds of this number can be written as:

`(2)/(3)x`

Then "plus 4" means add 4 we get:

`(2)/(3)x + 4`

"is 7" means that the above expression is equal to 7 (as follows):

`(2)/(3)x + 4 = 7`

The solution of the above equation is:

`(2)/(3)x + 4 = 7 \\ (2)/(3)x = 3 \\ x = (9)/(2)`
