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

$\begin{gathered} \frac{3y}{3}=\frac{3}{3} \\ y=1 \end{gathered}$

The solution is (2, 1)
