4x + y = 1
-2x - y = -8
2x = -7
x = -7/2
2(-7/2) + y = 8
-7 + y = 8
y= 15

Step-by-step explanation:
Angles in triangles are equal to 180. Substract the 2 known angles to get your answer.
Since they want a product, that means multiplication. We want to multiply a whole number and a fraction to get 5/3. When we multiply fractions, you multiply across the numerator and across the denominator. So in this case we want to multiply 2 numbers to get 5 a decimal 2 numbers to get 3. Each of these numbers only have 2 factors so
5 × 1 = 5 and
3 × 1 = 3
So we are going to multiply
5 × 1/3 =
5/1 × 1/3 = 5/3
