Step-by-step explanation:

a 4y=19-3

4y=16

y=16/4

y=4

b. 1/2n=5+3

1/2n=8

n=8×2 as 1/2 become on right so it become 2

n=16

Hi1315

Step-by-step explanation:

[tex]4y + 3 = 19 \\ 4y = 19 - 3 \\ 4y = 16 \\ \frac{4y}{4} = \frac{16}{4} \\ y = 4[/tex]

[tex]( \frac{1}{2} )n - 3 = 5 \\ \frac{n}{2 } - 3 = 5 \\ \frac{n}{2} = 5 + 3 \\ 2 \times \frac{n}{2} = 8 \times 2 \\ n = 16[/tex]
