Question

pfvr alguem me ajuda urgente a responder preciso da conta e da resposta

3(x+2)-1=2(x+3)-7
3(x+3)+2=5+2(x-1)
5(2x+7)-1=4(x-5)+9
2(x-1)+5(x-1)=7
2(2x-1)+3(x+1)=4(x+2)
2(2x+3)-5(x+1)=8

Answer 1

a) 3x+6-1=2x+6-7
3x-2x=6-7-6+1
x=-6

b) 3x+9+2=5+2x-2
3x-2x=5-2-9-2
x=-8

c) 10x+35-1=4x-20+9
10x-4x=-20-35+9+1
6x=-55+10
6x=-45
x=-7,5

d) 2x-2+5x-5=7
7x=7+5+2
7x=14
x=2

e) 4x-4+3x+3=4x+8
7x-4x=8+4-3
3x=9
x=3

f) 4x+6-5x-5=8
4x-5x=8-6+5
-x=7 .(-1)
x=-7
