Question

The sum of two numbers is 26 . The second number is two less than three times the first number. find the numbers​

Answer 1

Resposta:

x = 7

y = 19

Explicação passo a passo:

x + y = 26

y = 3x - 2

x + y = 26

x = 26 - y

y = 3x - 2

y = 3(26 - y) - 2

y = 78 - 3y - 2

y = 76 - 3y

y + 3y = 76

4y = 76

y = 76 / 4

y = 19

x = 26 - y

x = 26 - 19

x = 7
