Question

A)2x=16
b)x=-5
c)2x+14=5x-1
d)2.(3x-1)+2.(3x)=0
e)7.(x-1)+2.(3x+1)
f)2.(3-y)+7.(2-y)=15-4y

Answer 1

a)2x=16
x=16/2
x=8

b)x=-5

c)2x+14=5x-1
2x-5x=-1-14
-3x=-15
x=-15/-3
x=5

d)6x-2+6x=0
6x+6x=2
12x=2
x=2/12
x=1/6

e)7x-7=6x+2
7x-6x=2+7
x=9

f)6-2y+14-7y=15-4y
-2y-7y+4y=15-6-14
-9y=15-20
-9y=-5
y=-5/-9
y=5/9

espero ajudar ❤
