Question

hola nesecito q me ayeden con estos a )4x+1+2×(5+x)=x+71 b)21+3(2x-2)-2x=60-x son ecuaciones

Answer 1

4x + 1 + 2 (5 + x) = x + 71

4x + 1 + 10 + 2x = x + 71

6x + 11 = x + 71

6x - x = 71 - 11

5x = 60

x = 60/5

x = 12
------------------------------------

21 + 3 (2x - 2) - 2x = 60 - x

21 + 6x - 6 - 2x = 60 - x

15 + 4x = 60 - x

4x + x = 60 - 15

5x = 45

x = 45/5

x = 9
