Answer:
Substitute 3x - 5 for y in the second equation.
Step-by-step explanation:
Generally, to solve the system of linear equations of x and y, the first step would be trying to eliminate x (or y).
Then turn the system into the equation of only y (or x).
Next, try to solve for y (or x).
Then substitute the solved y (or x) into the original system to work out x (or y).
**********
3 options (1 addition, 2 subtractions) do not eliminate x or y (x and y still exist after manipulation).
=> Remaining option relating substitution would be a reasonable choice.

Answer:
_14
Step-by-step explanation:
step1 18×2 -50
step2 18×2 =36_50
step3 36_50=_14
2y-7x=-9
4x+6=y
2(4x+6)-7x=-9
8x-7x=-12-9
x=-21
y=4(-21)+6
y=-84+6
y=-78
