Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Let h be horses
let s be sheep
h + s = 28
6s = h
plug h into eq’n one
(6s) + s = 28
7s = 28
s = 4
plug s into eq’n 2
6(4) = h
24 = h
therefore there are 24 horses and 4 sheep
