Question

let us write the value of x by putting 7-4x/-5 instead of y in the equation 2x+3y=9​

Answer 1

Answer:

Given let

be put instead of y in the equation 2x + 3y = 9.

We have to find the value of x.

⇒ 22x – 21 = 9 (5)

⇒ 22x – 21 = 45

⇒ 22x = 45 + 21

⇒ 22x = 66

⇒ x = 3

∴ Value of x is 3.
