h) 4y=8
i) 4x-2=6
j) 2x-8=3x-10. me ajudem pfv preciso para amanha​

Answer 1

f) 2x-4=17-2x+1

2x+2x = 18+4

4x = 22

x = 22/4 ÷(2)

x = 11/2

g) 8x-15=38

8x = 38+15

8x = 53

x = 53/8

h) 4y=8

y = 8/4

y = 2

i) 4x-2=6

4x = 6+2

4x = 8

x = 8/4

x = 2

j) 2x-8=3x-10

2x-3x = -10+8

-x = -2 .(-1)

x = 2
