Question

9) Determine x
a) 6x = 2x + 16
b) 2x - 5 = x + 1
c) 2x + 3 = x + 4
d) 5x + 7 = 4x + 10
e) 4x - 10 = 2x + 2
f) 4x - 7 = 8x - 2
4x7= 8x - 2 2
g) 2x + 1 = 4x - 7
h) 9x + 9 + 3x = 15​

Answer 1

Resposta:

a_ 4x=16

x=4

b_ 3x=6

x=2

c_ x=1

d_ x=3

e_ 2x=12

x=6

f_ -4x=5

x=-1,25

g_ -2x=-8

x=4

h_ 12x=6

x=0,5
