Question

2x+7y+7x=18
Find the value of Y​

Answer 1

y=−9/7x+18/7

Explanation:

2x+7y+7x=18

9x+7y=18

Step 1: Add -9x to both sides.

9x+7y+−9x=18+−9x

7y=−9x+18

Step 2: Divide both sides by 7.

7y/7=−9x+18/7

y=−9/7x+18/7

Answer 2

Given :

• 2x + 7y + 7x = 18

To Find :

• The value of y

Solution :

`\qquad { \dashrightarrow \: { \sf{2x + 7y + 7x = 18}}}`

Adding the like terms :

`\qquad { \dashrightarrow \: { \sf{ 7y + 9x = 18}}}`

Transposing 9y to the other side which then becomes negative :

`\qquad { \dashrightarrow \: { \sf{ 7y = 18 - 9x}}}`

Dividing both sides by 7 :

`\qquad { \dashrightarrow \: { \sf{ (7y)/(7) = (18 - 9x)/(7) }}}`

`\qquad { \dashrightarrow \: { \sf{ y = (18 - 9x)/(7) }}}`

⠀

Therefore, the value of y = 18 – 9x/7 .
