Question

What is two-thirds a number plus 4 is 7

Answer 1

2/3x + 4 = 7
-4 -4
4 cancels out.
2/3x = 3
x 3 x3
6/3 = 2x = 9
/2 /2
2 cancels out.
x = 9/2 = 4.5

Answer 2

`two-thirds: (2)/(3) \\ number: b \\ plus: + (add) \\ 4: 4 \\ is: equal (to) \\ 7:7 \\ \\ \\ \\ Problem: (2b)/(3) + 4 = 7`

Finding our answer (if we had to solve it as well)↓


`(2)/(3)b + 4 - 4 \\ 7 - 4 = 3`


`(2)/(3)b = 3`


`(3)/(2) ( (2)/(3))` (← cancel this out because that would give you a
`1` by itself
`(3)/(2) (3) = (9)/(2)`


`Answer: B = (9)/(2)`
