Answer 1

Answer:

y=3..so..5x+2×3=-4...5x+6=-4...5x= -6-4...5x= -10 x= -2...so m=-2...option b

Answer 2

Answer:

b) -2

Step-by-step explanation:

(m,3) = (x,y)

therefore:

• x = m
• y = 3

now put value of y in given equation (5x+2y= -4)

5x + 2(3) = -4

5x + 6 = -4

5x = -4-6

5x = -10

x = -10/5

x = -2
