Question

alguem pode responder essas questões de equação de 1 grau
a)
b) 10X+60 = 0
c) -9x + 8 = - 43
d) 4X + 40 = 60
e) 4,5X + 18 = 0
f) 2,5X-20 = 0
g) 4X+5 = 2X+1
h) 4x-7 = 3x+ 1

Answer 1

b) 10X+60 = 0

10x = 60

X=60:10

X=6

c) -9x + 8 = - 43

43 + 8= 9x

51=9x

51:9=x

X=5,66

d) 4X + 40 = 60

4x=60-40

4x=20

X=20:4

X=5

e) 4,5X + 18 = 0

X=18-4,5

X=13,5

f) 2,5X-20 = 0

X=20-2,5

X=17,5

g) 4X+5 = 2X+1

4x-2x=1-5

2x=-4

X=-2

h) 4x-7 = 3x+ 1

4x-3x=7+1

X=8
