Question

porfavor es para mi nota final

Answer 1

Explicación paso a paso:

1) 10x= - 5x + 60

10x + 5x= 60

15x =60

X=4

2) 4x + 1 = x + 4

4x - x= 4 - 1

3x= 3

X=3/3=1

3) ( 2x - 9)/3 = ( 3x + 4)/12

12 (2x - 9) = 3 ( 3x +4)

24x - 108 = 9x + 12

24x - 9x = 12 + 108

15x = 120

X= 120/15

X=8

4) 5( x + 2) - 8 = 4 ( x + 12) - 1

5x + 10-8 = 4x + 48 - 1

5x - 4x = 47 - 2

X = 45
