Question

quien me ayuda con estas ecuaciones 6/5+2x=7 16-24=2x+14 4(x-10)=-6(2-x)

Answer 1

6/5 + 2x = 7           mcm = 5
6 + 10x = 35
10x = 35 - 6
10x = 29
x = 29/10



16-24 = 2x+14
-8 = 2x + 14
-8-14 = 2x
-22 = 2x
-22/2 = x
-11 =x


4(x-10)=-6(2-x)
4x - 40 = -12 + 6x
-40+12 = 6x-4x
-28 = 2x
-28/2 = x
-14 = x
