Question

Me ajudeeeeeem equação de primeiro grau
a x- 50 = 17

b 17x= 41 + 17

c 8 (2 x - 5) = - 16

d 10 (2x +1) = + 20

e 3 (3x + 5) = -15

Answer 1

a)
x- 50 = 17
x=17+50
x=67

b)
17x= 41 + 17
17x=58
x=58/17

c)
8 (2 x - 5) = - 16
16x-40=-16
16x=-16+40
16x=24
x=24/16
x=3/2

d)
10 (2x +1) = + 20
20x+10=20
20x=20-10
20x=10
x=10/20
x=1/2

e)
 3 (3x + 5) = -15
9x+15=-15
9x=-15-15
9x=-30
x=-30/9
x=-10/3
