Question

write as
equation and solve:
a) A number decreased by 5
is 23​

Answer 1

23+5

Step-by-step explanation:

let the unknown number be X

X is decreased by 5

meaning we'll have to take away 5

so x-5

then x when it is decreased by 5 it gives 23

x-5=23 is the equation

now add 5 on both sides of the equation

giving X = 23+5

that is your answer

which means the number is 28
