Answer:
x − y = −3
Explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
Ax+By=C
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
1x+3=y
Move all terms containing variables to the left side of the equation.
Multiply x by 1.
x+3=y
Move y to the left side of the equation because it contains a variable.
x+3−y=0
Move 3 to the right side of the equation because it does not contain a variable.
x−y=−3
