-11 is your answer. To get this, you should follow 'PEMDAS' which stands for P-parenthesis, E-exponents, M-multiplication, D-division, A-addition, S-subtraction. Which ever comes first, is how you solve your problem. Therefore, in your case, add the positives first, then subtract. Hope this helped!

Answer:
Ummmm... Yeah... Its no solution
Step-by-step explanation:
So, if y = 1, then all you have to do is plug in 1 for y in the first equation! :)
2x + 4y = 10
2x + 4(1) = 10
Simplify.
2x + 4 = 10
Subtract 4 from both sides.
2x = 6
Divide both sides by 2.
x = 3
So, your answer is a) x = 3, y = 1
