Step-by-step explanation:
100:
25x4=100
50x4=200g
75x4=300g
75x4=300g
100x4=400ml
40:
25x1.6=40
50x1.6=80g
75x1.6=120g
75x1.6=120g
100x1.6=160ml
Answer:
(-2, 5)
Step-by-step explanation:
I will assume that your system is
y = -4x - 3
y = -2x + 1
Multiplying the second equation by -2 results in
y = -4x - 3
-2y = 4x - 2
combining these two equations eliminates x temporarily:
-y = -5, so that y must be 5.
Substituting 5 for y in the second equation, we get:
5 = -2x + 1, or
4 = -2x, which results in x = -2
and so the solution is (-2, 5)
