I think the answer is B. Or A.
Easy, you're just reversing multiplication. divide 13.65 by 1.5 to get 9.1
n=9.1
RemarkThe very easiest way to do this is by substitution. The ys are isolated on the left. When you equate what's on the right, you can solve this for 1 variable, the xs.
Substitute and solve8x - 9 = 4x -1 Subtract 4x from both sides.
8x - 4x - 9 = - 1
4x - 9 = - 1 Add 9 to both sides.
4x = - 1 + 9
4x = 8 Divide by 4
x = 8/4
x = 2
Solve for yUse either equation to solve for y.
y = 4x - 1
y = 4(2) - 1
y = 8 - 1
y = 7
