Question

a) -x + 2,999= 7,248
b) 47+38+x=110
c)-2x-1,000=0
d)2x-1,000=1,500
e)350x-500=100x + 750

Answer 1

Resposta:

A = X=   -  4,249

B = X= 25

C = X= -500

D = X =1250

E = X = 5

Explicação passo a passo:

A) -X = 7248-2999 ---- -X=4249 ----- X= - 4249

B) X= 110-47-38        X=25

C) - 2X = 1000       -X=1000/2    -X=500       X= - 500

D) 2X = 1500+1000      2X=2500  X=2500/2     X=1250

E) 350X-100X = 750 + 500     250X = 1250    X=1250/250      X= 5
