I will show you how to solve by elimination. You have two equations. The goal of this method is to cancel out one of the variables.

3y=x-1

x-2y=2 ----> 2=x-2y (just flipping it around visually)

If we align the two equation and subtract them...

3y=x-1

-(2=x-2y)     "x is canceled out"

---------------

3y-2=-1+2y  "one variable equation now"

y=1

Plug in 1 for y into any equation to get corresponding x value.

3y=x-1

3(1)=x-1

x=4

Answer: (4,1)

Natalija [7]
Step 1. Multiply 5 by y and you get 5y
Step 2. Multiply 5 by .4(2/5)
Step 3. Your equations will look like 5y+2=-13
Step 4. Subtract 2 from its self and -13
Step 5. Your equation will be 5y=-15
Step 6. Divide 5 from both sides
Step 7. Your answer is y=-3
