Question

Solve 28 + 7y =91Y=.....​

Answer 1

Answer:

$y = 9$

Step-by-step explanation:

$28 + 7y = 91 \\ 7y = 91 - 28 \\ 7y = 63 \\ \frac{7y}{7} = \frac{63}{7} \\ y = 9$

Answer 2

Answer:

Y=9

Step-by-step explanation:

28 + 7y =91

first subtract 28 from both sides

28-28+7y=91-28

7y= 63

then divide both sides by 7

7y/7=63/7

y=9

ANSWER CHECK

to see if the answer is correct substitute the answer you got for the variable

y=9

28 + 7(9)

multiply 7 and 9

7(9)=63

63+28= 91
