Solve by substitution method
please show step by step so i can understand better. I keep getting it wrong at the end.
Subtract 2x from both sides of 2x+y=14.
y = 14-2x
Substitute 14-2x for y in second equation and solve for x. Insert that value into the first equation and solve for y. Check by inserting both values into the second equation.
