Solve the simultaneous equations 2x-5y=9 and 3x+4y=2

The answers are:

Step-by-step explanation:

In order to determine the solution for x and y, we have to solve both equations. We use the elimination method, where we eliminate the same variable in both equations.

In this method, we need to have the same coefficient in the eliminated variable, but different sign.

In this case, we choose to eliminate "x" variable. The minimum common multiple (mcm) between the coefficients of "x" is 6. So the first equation is multiplied by 3 and the second equation is multiplied by -2.

Then, we replace the value of "y" in any equation.

Finally, the solution for both variables is:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
