Respuesta :
Answer:
Solve for x in the second equation.
Step-by-step explanation:
Subtract 3x from both sides and you can substitute y in the second equation for the first equation and solve for x.
Solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions. Option B is correct.
What is the system of two equations?
A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The given equation in the problem is;
Equation 1: 3x + y = 9
Equation 2: 5x-3y=1
Equation 1;
3x + y = 9
y=9-3x
Equation 2:
5x-3y=1
5x+3(9-3x)=1
5x+27-9x=1
-4x=-26
x =6.5
Hence, solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions.
Hence, option B is correct.
