Question

RESOLVA AS EQUAÇÕES.

(b) -2x= 10

(c) 3x+2=2x-11

(d) 2x+14=5×-1

(e) 5x+4-2×=26-3x

(f) ×/2 +1=x+3

(g) 3×(x-2)-(1-x)=13

(h) x-(x+1)=12-(3x-2)​

Answer 1

b) -2x= 10 •(-1) -> 2x= -10 -> x= -10/2 -> x= -5
c) 3x-2x= -11 + (-2) -> x= -13
d) 2x-5x= -1 + (-14) -> -3x= -15 •(-1) -> 3x= 15 -> x= 15/3 -> x= 5
e) 5x-2x+3x= -4+26 -> 6x= 22 -> x= 22/6
