Question

a) x-196=0 b)5x+10x=0 c) 2x+20=x-15 d) 8x+30=-2x+60 e)2x+5x+3=0 f) 3x+4x+1=0

Answer 1

a) x = 196
b) x = 0
c) x = -35
d) x = 3
e) x = -3/7
f) x = -1/7

Answer 2

(a) x - 196 = 0
x = 196

(b) 5x + 10x = 0
15x = 0
x = 0/15
x = 0

(c) 2x + 20 = x - 15
2x - x = -15 - 20
x = -35

(d) 8x + 30 = -2x + 60
8x + 2x = 60 - 30
10x = 30
x = 30/10
x = 3

(e) 2x + 5x + 3 = 0
7x = -3
x = -3/7

(f) 3x + 4x + 1 = 0
7x = -1
x = -1/7



Espero ter ajudado.
