Five times the sum of a number and 4 equals 3.

use the variable b for unknown number

equation : 5(b+4) = 3

b = -17/5

Step-by-step explanation:

let b be the number

"sum of a number and 4" ---> ( b + 4)

"five times" > 5(b+4)

"equals 3 " > 5(b+4) = 3

Solving for b

5(b+4) = 3

5b + 4(5) = 3

5b + 20 = 3

5b = 3 - 20

5b = -17

b = -17/5

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.

1. 3

2. 4

3. 1

hope this ! have a great day.
