The correct answer is 5b + 1 = 3b + 5. In order to find the answer to a system of equations, the two equations must be set equal to each other. For instance, if we had the equations x = y + 1 and x = 3y - 1, we would set the two equations equal to one another to find the answer.
x = y + 1 x = 3y - 1 y + 1 = 3y - 1 1 = 2y - 1 2 = 2y 1 = y
x = y + 1 x = 1 + 1 x = 2
You can use the same procedure with this system of equations.
We can see that the given set of equations represent system of linear equation.
We will use substitution property of equality, which states when , then x can be substituted in any equation in place of y and y can be substituted in place of x in any equation as well.
To solve our given system of equations we need to equate our given equations as:
