Question

Ayudenme a comprobar estas 2 ecuaciones:
"5x-9-104+20x=45-6+5x"
x=38/5
"3(4x+1)=5(2)+5(2x+1)"
x=6

Answer 1

1)
5x-9-104+20x=45-6+5x
25x - 113 = 39 + 5x
25x - 5x = 39 + 113
20x = 152
X = 152/20 mitad
X = 76/10 mitad
X = 38/5 no se puede reducir mas

X = 38/5


2)
3(4x+1)=5(2)+5(2x+1)
12x + 3 = 10 + 10x + 5
12x + 3 = 15 +10x
12x - 10x = 15 - 3
2x = 12
X = 12/2
X = 6
