Question

what is the solution of the equation 3x-y=4?

Answer 1

3x-y=4
3x=4+y
x=4+y/3
therefore if y=2so,
x=4+2/3
x=6/3
x=2

Answer 2

The solution of the equation is $x=\frac{4+y}{3}$

Step 1:  Slove for $x$

Given: $3x-y=4$

To solve for x by using given equations

Add y on both side of the given equations

$3x-y+y=4+y$

we get

$3x=4+y$

now divide both side by $3$

we get

$x=\frac{4+y}{3}$

Hence the solution of the equation is$x=\frac{4+y}{3}$
