Solving Linear Equations Using Substitution Method

What is the first step in solving a pair of linear equations using the substitution method?

• Add the equations together

• Substitute one equation into the other

• Multiply both equations by a constant

• Divide one equation by the other

In the given problem, which equation is used to express one variable in terms of the other?

• X + Y = 14

• X + Y = 4

• X - Y = 4

• X - Y = 14

After substituting the value of X in terms of Y, what is the next step?

• Multiply both equations

• Add both equations

• Solve for X

• Solve for Y

What is the value of Y obtained after solving the equations?

• 14

• 9

• 5

• 4

What is the final value of X after substituting the value of Y back into one of the equations?

• 14

• 9

• 5

• 4
