Question

rexolvati in R ecuatia
16x-3(x+1)=5x
2,5(x-4)-6x=3-x
va rog e urgent dau coronita

Answer 1

16x - 3x - 3 = 5x
16x - 3x - 5x = 3
8x = 3
x = 3/8

2,5x - 10 - 6x = 3 - x
2,5x - 6x + x = 10 + 3
- 2,5x = 13
x = 13/2,5

Answer 2

1)16x-3(x+1)=5x            
16x-3x-3=5x                    
13x-3=5x
8x=3 
x=3/8
2)2,5x-10-6x=3-x
-3,5x-10=3-x
-3,5x+x=10+3
-2,5x=13
x=-5,2
