When we add two equations, it's important to <em>combine like terms</em>
<u>x's with x's </u>
<u>y's with y's </u>
<u>and constants with constants</u>
2x + 5x = 7x
3y + (-y) = 2y
-5 + -12 = -17
Let's put <em>everything together </em>for a final equation
7x + 2y - 17 = 0
or
7x + 2y = 17
Make an expression
45(5)+12
Solve:
225+12
=237
So your answer is 237 dollars
It’s D because 2x6 is 12 then 3x2 is 6 then 12-6=6
Answer:
its D
