The first step in solving using the substitution method is __________.

Back

get either variable by itself

Front

Which variable should you isolate first in the system? 3x + 2y = 10 x - 5y = 18

Back

The x in the second equation

Front

What is the correct first step in solving this system by substitution?
x = 2y +11
-7x -2y = -13
Options: -7(2y+11) - 2y = -13, -7x -2(2y +11) = -13, 2y+11-2y = -13

Back

-7(2y+11) - 2y = -13
