Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20
Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)

Answer:
20 = 6m or m = 20/6 = 10/3
Step-by-step explanation:
Let's say Samantha has s marbles and Paul has m marbles.
We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.
Substitute 20 in for s:
20 = 6m
m = 20/6
Thus, the equation is m = 20/6.
