17 and 53.

Step-by-step explanation:

Let the two unknown numbers be x and y respectively.

Translating the word problem into an algebraic expression, we have;

x + y = 70 equation 1

x - y = 36 equation 2

From equation 1;

x = 70 - y equation 3

Substituting eqn 3 into eqn 2, we have;

70 - y - y = 36

70 - 2y = 36

70 - 36 = 2y

2y = 34

y = 17

Next, we find x;

x = 70 - y

x = 70 - 17

x = 53

step-by-step explanation:

do you have a copy of the table?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
