Answer 1

Answer:

7y = 14

y = 14/7

y= 2 ( since 7 × 2 = 14)

Answer 2

$\huge\bf\mathfrak\green{An}\red{sw}\blue{er} \\ \: is \: \huge\bf\orange{7y = 14}$

$1) 2y - 3 = 15 \\ 2(2) - 3 = 15 \\ 4 - 3 \: is \: not \: equal \: to \: 15 \\ \huge\bf\red{wrong}$

$2) 7y = 14 \\ 7(2) = 14 \\ there \: fore \: 14 = 14 \\ \huge\bf\green{correct}$

$3) 8y + 1 = 4 \\ 8(2) + 1 = 4 \\ 16 + 1 = 4 \\ 17 \: is \: not \: equals \: to \: 14 \\ \huge\bf\red{wrong}$

$4) y + 1 = 5 \\ 2 + 1 = 5 \\ there \: fore \: 3 \: is \: not \: equals \: to \: 5 \\ \huge\bf\red{wrong}$
