Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)

Answer:
Option C: (5/4)x - 2 = (3/2)x - 4
Step-by-step explanation:
A) (5/2)x + (7/2) = (3/4)x + 14
Multiply through by 4 to get;
10x + 14 = 3x + 56
10x - 3x = 56 - 14
7x = 42
x = 42/7
x = 6
B) (5/4)x - 9 = (3/2)x - 12
Multiply through by 4 to get;
5x - 36 = 6x - 48
6x - 5x = 48 - 36
x = 12
C) (5/4)x - 2 = (3/2)x - 4
Multiply through by 4 to get;
5x - 8 = 6x - 16
6x - 5x = 16 - 8
x = 8
D) (5/2)x - 7 = (3/4)x + 14
Multiply through by 4 to get;
10x - 28 = 3x + 56
10x - 3x = 56 + 28
7x = 84
x = 84/7
x = 12
