Question

resolva as equaçoes
A)4x + 3 = -19
B) 5x+2=2x-1
C) 6-3x= -10 - 4x

Answer 1

a) 4x+3=-19
4x=-19-3
4x=-22
x=-22/4 (÷2)
x=-11/2
b) 5x+2=2x-1
5x-2x=-1-2
3x=-3
x=-3/3
x=-1
c) 6-3x=-10-4x
-3x+4x=-10-6
x=-16

Answer 2

$A)4x + 3 = -19\to 4x=-19-3\to 4x=-22\to x=- \frac{22}{4} \to \\\\x=- \frac{11}{2}~ou~x=5,5 \\\\\\ B) 5x+2=2x-1 \to 5x-2x=-1-2\to 3x=-3\to x=- \frac{3}{3}\to \\\\ x=-1\\\\\\ C) 6-3x= -10 - 4x\to -3x+4x=-10-6\to x=-16$
