b)5×+3=4×+18
c)2×/5=8
d)4×-1=11
e)11×+12=9×+13
f)5×=4×+12​

Answer 1

A) 2x+1=3x+16

2x-3x=16-1

-x=15

x= -15

B) 5x+3=4x+18

5x-4x=18-3

x=15

C) 2x/5=8

2x=8*5

2x=40

x=40/2

x=20

D) 4x-1=11

4x=11+1

4x=12

x=12/4

x=3

E) 11x+12=9x+13

11x-9x=13-12

2x=1

x=1/2 ou x=0,5

F) 5x=4x+12​

5x-4x=12

x=12
