Y-2x=-3.5
x-2y=-14
then multiply the first term by 2
2y-4x=-7
x-2y=-14
then sum them
-3x=-21
x=-7
y=3.5

we know that

The circumference of the circle subtend a central angle of 360 degrees

uing a proportion

Find out the central angle for an arc of length 32/5

$\frac{8}{360^o}=\frac{(32/5)}{x}\\\\x=360(32/5)/8\\\\x=288^o$

3+ 1/4X=2 Solve for X

Shalnov [3]

3 + 1/4x = 2.....subtract 3 from both sides
1/4x = 2 - 3
1/4x = -1...multiply both sides by 4, eliminating the 4 on the left side
x = -1 * 4
x = -4
