Question
Write two solutions for the following equation :
3x + 4y = 7
Solution
Given that 3x + 4y = 7
Substituting `x = 0 ` in this equation, we get
`3 xx 0 + 4y = 7`
⇒ ` y = 7/4`
So. `(0. 7/4)` is a solution of the given equation substituting `x = 1 ,` in given equation. We get
⇒ `3 xx 1 + 4y = 7`
⇒ 4y = 7 - 3
⇒ = 4
⇒ y = 1
So, (1.1) is a solution of the given equation
∴ `(0. 7/4)` and (1.1) are the solutions for the given equation.
