B) 28×50, then take the answer - 1100
Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
3x -12 = -36
-36 ÷ -3 = 12
-7 + 12 = 5
The person at the top is correct.
Im honestly not sure but I’m thinking answer A?
