Question

2x+3y=7 find the same solution

Answer 1

The given equation is

`2x+3y=7`

To find a solution we must choose a value of x, then find the corresponding value of y

Let us choose x = 2

Substitute x in the equation by 2

`2(2)+3y=7`

Then let us find the value of y

`4+3y=7`

Subtract 4 from both sides

`\begin{gathered} 4-4+3y=7-4 \\ 3y=3 \end{gathered}`

Divide both sides by 3

`\begin{gathered} (3y)/(3)=(3)/(3) \\ y=1 \end{gathered}`

The solution is (2, 1)
