Question

Nesesito saber esta ecuacion y su comprobacion 21-7X=41X-123

Answer 1

21-7x = 41x-123
21+123 = 41x+7x
144 = 48x
144/48 =x
X=3
Comprobacion
21-7x = 41x-123
21-7(3) = 41(3)-123
21-21 = 123-123
0 = 0

Answer 2

-7X-41X=-21-123
-48X=-144
X=-144/48
X=3
COMPROBACION
21-7(3)=41(3)-123
21-21=123-123
0=0
