Answer:
{x,y} = {2,7}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = -4x + 15
// Plug this in for variable y in equation [2]
[2] 3x + 5•(-4x+15) = 41 [2] -17x = -34
// Solve equation [2] for the variable x
[2] 17x = 34 [2] x = 2
// By now we know this much :
x = 2 y = -4x+15
// Use the x value to solve for y
y = -4(2)+15 = 7
28:21
because the same number has to multiply both sides of the ratio. so number = 7 and:
4x 7 = 28
3 x 7 = 21
Answer: x=0 hope this helps
