Question

If x+3y=7 and y=2, then x equals?

Answer 1

Hello :)

Answer:

x = 1

Explanation:

Our task is to find x when y = 2.

`\sf{x+3y=7\phantom{111111111111111}\mid y=2`

`\sf{x+3(2)=7}`

`\sf{x+6=7}`

`\sf{x=1}`

Henceforth, x = 1.

Answer 2

x + 3y = 7

at y = 2

Then,

x + 3(2) =7

x + 6 = 7

x = 7 - 6

x = 1
