5 1/6 * (-2/5) = __
turn 5 1/6 into a mixed fraction
31/6 * (-2/5) = __
multiply
31 * -2 = -62
6 * 5 = 30
so -62/30 or -2 1/15

9x - y = 15
2x + 8y = 28
Use the substitution method.
Solve for y in the first equation.
9x - y = 15
-y = 15 - 9x
y = -15 + 9x
Now plug in y into the second equation.
2x + 8(-15 + 9x) = 28
2x - 120 + 72x = 28
74x - 120 = 28
74x = 148
x = 2
Plug x back into the rewritten first equation.
y = -15 + 9(2)
y = -15 + 18
y = 3
x = 2, y = 3
Answer:
15
Step-by-step explanation:
18-x=3
18-3=x
18-3=15
