I would actually use division. So divide 56 by 8, and you'll get 7.
Or you can multiply 7 times 8 and get 56.
Hope this helps!

Answer:
{x,y}={−5,−7}
Explain:
// Solve equation [2] for the variable y [2] 3y = 7x + 14 [2] y = 7x/3 + 14/3 // Plug this in for variable y in equation [1] [1] 8x - 3•(7x/3+14/3) = -19 [1] x = -5 // Solve equation [1] for the variable x [1] x = - 5 // By now we know this much : x = -5 y = 7x/3+14/3 // Use the x value to solve for y y = (7/3)(-5)+14/3 = -7 Solution : {x,y} = {-5,-7}

Answer:
60
Step-by-step explanation:
Let the number of dog owners and cat owners be 4x and 5x
4x = 48
x = 48/4
x = 12
Therefore 5x = 5×12
= 60
Answer:
x = -12
y = 3
