Find x so that (x,-14) is a solution to 2x+3y=12

27

Question:

Find so that is a solution to .

Step-by-step explanation:

So we are asked to replace with -14 and solve for in the equation:

.

with :

Add 42 on both sides:

Divide both sides by 2:

.

So the -coordinate that corresponding to is .

Verify that:

is a point satisfying .

Replace with 27 and with -14:

is true so our work must be right.
