I need help 6x-2y=10 x-2y=-5 solve by elimination

To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.

There as we can get rid of the y-term by adding both equations.

Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.

Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.

First Equation

Second Equation

Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)

answer is : muchas/tipicas

have a nice day!
