What is the correct first step in solving this system by substitution?
-7(2y+11) - 2y = -13
-7x -2(2y +11) = -13
2y+11-2y = -13
The first step in solving using the substitution method is __________.
get x by itself
get y by itself
get either variable by itself
add the equations together
Which answer has a correct first step for this system:
The variable is already isolated, so we've already solved the system.
The variable is already isolated for y, so we substitute it in the first equation and solve for x
3x + 3(3x + 5) = 3

The variable is already isolated for y, so we substitute it in the second equation and solve for x
y = 3(3x + 3y) = 3
