Hey bro not the best but remember too use PEMDAS
Y= (2x-20)/ 5 then you replace y so with a simple calculation u get x than u replace x with it value to get y as simple as that
Answer:
(–19, 55)
Step-by-step explanation:
y = –3x – 2 equation 1
5x + 2y = 15 equation 2
using equation 1 in equation 2 we have:
5x + 2(–3x – 2) = 15
5x –6x – 4 = 15
-x = 15+4
x=-19
using equation 1:
y = -3(-19)- 2
y= 57-2
y= 55
Answer: If the answer needs to be simplified, then the answer would be
-20c^2 d^3 - 16cd^2
