One number exceeds another by 26. the sum of the numbers is 58. what are the numbers
Gnom [1K]
First number = X

second number = x +26  ( exceeds means higher so add 26)

x + x+26 = 58

combine like terms:

2x + 26 = 58
 subtract 26 from each side:

2x = 58-26

2x = 32

divide both sides by 2:
x = 32/2
x = 16

first number is 16
second number = 16+26 = 42

QveST [7]
X representa o numero das suas respostas certas.
y represnta o numero das suas respostas erradas.
O total de perguntas <span>é 25, portanto
x + y = 25

Agora tratamos do dinheiro.
Come</span>ça com <span>R$ 500,00
Pelas x respostas certas, recebe 200x.
Pelas y respostas errads perde 150y.
O total de dineheiro inicial mais os ganhos menos as perdas s</span>ão iguais a
R$ 600,00, portanto
500 + 200x - 150y = 600
200x - 150y = 100
20x - 15y = 10

Temos um sistema de duas equações com duas variaveis.

<span>x + y = 25</span>
20x - 15y = 10

      15x + 15y = 375
+    20x - 15y = 10
---------------------------
       35x         = 385
           x         = 11

x + y = 25

11 + y = 25

y = 14
