Hi there!

The expression you would use would be a + 3.

Because we do not know the age for present so it is unknown. But when you add 3 years to her present age it becomes a expression.

Hope this helps :)

(4x+10)+(14x+3)=157

calculate for x

you'll get x=8

put 8 into NFE

14(8)+3=115

Likurg_2 [28]

Answer:

26

Step-by-step explanation:

Let the peter's number be represented    x

Given that

1. if you subtract 19 from my number

writing it mathematically it will be x -19

2. multiply the difference by -3

it can be written as

since difference is x-19

multiplied the difference with -3

-3(x-19)

3. the result is -21

-3(x-19) = -21

dividing both side by -3

-3(x-19)/-3 = -21/-3

x-19 = 7

adding 19 both sides

x-19 + 19  = 7 + 19

x = 26

Thus, peter's number is 26.
