Question

Determine o conjunto soluçao da equaçao
A) 7w + 3 = 2w +23
B) 2 (3P +1) = 11
C) 3 (2x+3) = 7x - 2




ME AJUDEM POR FAVOR !!!!

Answer 1

bom, equacao do 1° grau. Vamos lá.

A) 7w + 3 = 2w +23
7w-2w = 23-3
5w = 20
w= 20/5
w= 4✓

B) 2 (3P +1) = 11
6p + 2 = 11
6p=11-2
6p = 9
P= 9/6✓

C) 3 (2x+3) = 7x - 2
6x + 18 = 7x -2
18+2 = 7x-6x
x = 20✓

Answer 2

A) 7w + 3 = 2w +23 
7w-2w = 23-3
5w = 20
w= 20/5
w= 4

B) 2 (3P +1) = 11 
6p + 2 = 11
6p=11-2
6p = 9
p= 9/6
p=1,5

C) 3 (2x+3) = 7x - 2
6x + 9 = 7x -2
6x-7x= -2 - 9
-x = -11    (1 x 1)
x=11
