Question

Solve the system of linear equations by substitution y=x y=2x-1

Answer 1

Answer:

x=1

y=1

(1,1)

Step-by-step explanation:

TO SOLVE FOR X:

1. Substitute. You should start off by looking like this:

x=2x-1

2. Subtract 2x from both sides:

-x=-1

3. Make x positive by multiplying both sides by -1:

x=1

TO SOLVE FOR Y:

1. Substitute x into original statement:

y=2(1)-1

2. Simplify:

y=2-1

3. Simplify:

y=1

TO CHECK YOUR ANSWER:

1. Take other original statement and stubstitute answers. It should look like this:

y=x

1=1

2. Does 1=1?

Yes so the answer is correct

3. Final Answer is:

x=1

y=1
