Mary brother is five years younger than 3 times her age. the sum of their ages 39. how old is mary
butalik [34]
Let's say Mary's brother's age is x and Mary's age is y
(1) x = 3y - 5
(2) x + y = 39

Now if we substitute equation (1) into equation (2) we get:
3y - 5 + y = 39
4y = 44
y = 11

Therefor Mary is 11 years old

X+2y + z = 4<br> 1. 4y - 3z = 1<br> y + 5z = 6
Feliz [49]

Answer:

The values of x = y = z = 1  

Step-by-step explanation:

Given three linear equation as ,

x + 2y + z = 4               .......a

     4y - 3z = 1               .......b

       y + 5z = 6             ........c

Now solve eq a and b first

   4y - 3z = 1   ×  5

    y + 5z = 6  ×  3

Or, 20y - 15z = 5

      3 y + 15z = 18

so ,(20y - 15) + (3y +15 ) = 5 +18

or,   23 y = 23  

∴           y = 1

Now put this y value in eq c

so , 1 + 5z = 6 ,

Or,       5z = 6-1 =5

∴            z = 1

Again put this y and z value in eq a

so, x + 2(1) + (1) = 4

Or,                x   = 4 -3

∴                   x = 1

Hence from the above solutions , the value of x = y =z = 1        Answer
