Question

Kayla thought of a number, added 4, multiplied by 3, subtracted 5, and got 28 as her final result. What number did she start with

Answer 1

Answer:

The number is 7

Step-by-step explanation:

[{(x+4)×3}-5] = 28

3x+7=28

3x = 21

X = 7

Verification:

[{(7+4)×3}-5] =28

[{11×3}-5] =28

[33-5] =28

28 = 28

hence, proved lhs=rhs
