Question

podéis resolver estas ecuaciones por favor?
x-10=5(x-2)
2(x+5)-3x=x+18

Answer 1

x-10 = 5(x-2)
x-10 = 5x-10
-10+10 = 5x-x
0 = 4x
0/4 = x
x = 0

Comprobación
0 - 10 = 5 (0-2)
-10 = -10
****

2(x+5)-3x = x+18
2x+10-3x = x+18
2x-3x-x = 18-10
-2x = 8
x = 8/-2
x = -4

Comprobación
2(-4+5)-3(-4) = -4+18
-8+10+12 = 14
14 = 14
