Two numbers are 38 and 10

Step-by-step explanation:

Let x  and y are the two numbers

One number is 18 more than twice the other number.

The sum of the numbers is 48.

Plug in y =2x+18

Subtract 18 from both sides

divide both sides by 3

x=10

Two numbers are 38 and 10

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
