Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Let's solve ~

The given equations are :

`\qquad \sf  \dashrightarrow \:x + y = 32`

and

`\qquad \sf  \dashrightarrow \:y = 7x`

Now, plug in the value of y from equation 2 into equation 1 to find out the value of x ~

`\qquad \sf  \dashrightarrow \:x + y = 32`

`\qquad \sf  \dashrightarrow \:x + 7x = 32`

`\qquad \sf  \dashrightarrow \:8x = 32`

`\qquad \sf  \dashrightarrow \:x = 32 / 8`

`\qquad \sf  \dashrightarrow \:x = 4`

Now, plug the value of x in equation 2 to find y

`\qquad \sf  \dashrightarrow \:y = 7x`

`\qquad \sf  \dashrightarrow \:y = 7 * 4`

`\qquad \sf  \dashrightarrow \:y = 28`
