Question

Carla chose a number between 1 and 50 and then described to henry how he could determine the number she chose.Carla's says "if you subtract 5 from my number,multiply that quantity by 4,and then add 7 to the result,you get 35."write an equation that henry can solve to find carla's number.

Answer 1

you can use
4(x-5)+7=35

bc...

(4x -20)+7=35
(4x-20)-7=-7
(4x-20)=28
4x+20= =20
4x=48
4÷4=48÷4
x=12
carla guessed 12

hope this helped :)

Answer 2

(x-5) 4 + 7= 35
4x-20 + 7 = 35
4x- 13= 35
4x = 35+15
4x = 50
×= 50÷4
