Question

What is 2/3 a number plus 4 equals 7

Answer 1

9/2


7-4=3 ---- 3* (3/2)= 9/2

Answer 2

Two-thirds (
`(2)/(3)`) a number (n) plus (+) 4 equals (=) 7.



`(2)/(3)`n + 4 = 7 Subtract 4 from both sides

`(2)/(3)`n = 3 Multiply both sides by
`(3)/(2)` to cancel out the fraction (
`(2)/(3) x (3)/(2) = 1`) (3 x
`(3)/(2)` =
`(3 x 3)/(2)` =
`(9)/(2)` =
`4 (1)/(2)`
n = 4
`(1)/(2)`
