Answer 1

Respuesta:

Explicación paso a paso:

2 . (X + 4) = 18

 2x +  8  = 18

 2x = 18 - 8

 2x = 10

 x =10/2

 X =5

---------------------------------------------------

4 . (H + 6) = 2 . (H + 3)

4H + 24 = 2H + 6

4H - 2H = 6 - 24

2H = 18

H = 18/2

H=9

--------------------------------------------------

3 . (3Y + 2) + 4Y = 3 . (Y + 3) + 9

9Y + 6 + 4Y = 3Y +9 +9

9Y + 4Y -3Y = 9+9 -6

13Y - 3Y = 18-6

10Y = 12

y =12/10

Y =6/5
