System: x + y = 44; x = 2y + 2
Solve with substitution: x = 30; y = 14
x + y = 44
x = 2y + 2
Substitute 2y + 2 for x
2y + 2 + y = 44
3y + 2 = 44
Subtract 2 on both sides.
3y = 42
y = 14
Now substitute back in.
x + 14 = 44
Subtract 14 on both sides.
x = 30
<u><em>v=-6 is the right answer. </em></u> First you had to subtract by 7 from both sides of equation, and it gave us, 
. And then simplify, and it gave us, 
. You can also add by 8v from both sides of equation, and it gave us, 
. Next simplify, and it gave us, 
. Then you divide by 2 from both sides of equation, and it gave us, 
. And finally simplify, and it gave us the answer is <u><em>v=-6 is the right answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
