Solve the equation for w: 2/3 (w + 3) = 7

A. 3 1/3
B. 4
C. 6
D. 7 1/2

Answer 1

1. Multiply W by 2/3 = 2/3
2. Multiply 3 by 2/3 = 2
3. Subtract 2 from both sides
4. Multiply 5 and 2/3
5. Answer is 3 1/3

Answer 2

`(2)/(3) (w+3)=7`

`((2)/(3) )(w)+((2)/(3) )(3)=7` Simplify

`(2)/(3) w+2=7`

`(2)/(3) w+2-2=7-2` Subtract 2 from both sides

`(2)/(3) w=5`

`((3)/(2) )*((2)/(3)w)= (3)/(2) *5` Multiply both sides by
`(3)/(2)`

`\framebox{w=$(15)/(2)$}or\fbox{7.5}or\framebox{w=7$(1)/(2)$}`

So therefore, your answer would be D. 7 1/2

Hope this helps!
