She would have a total of 40 stamps.
Answer:
x/2
Step-by-step explanation:
2/2=1=y
4/2=2=y
6/2=3=y
0.03125 and 0.015625
hope this helps but im probably wrong
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
