(a) is correct and for (b) just substitute a variable
from eq.1 y = (32-3x)/2 now substitute y = (32-3x)/2 in eq.2 , and then you can find value of x , and after that put that value of x in any of the two equations to get the value of y as well.

short osprey (a) is correct and for (b) just substitute a variable from eq.1 y = (32-3x)/2...

x = 18.67 idk wut y equals bc its a negative? so idk y

#

oo

round talon x = 18.67 idk wut y equals bc its a negative? so idk y

When you solve for x , you get two solutions as it's quadratic in x, ignore the 17.56 one and use the other one i.e x = 1.1 and then solve for y using y = (32-3x)/2

xdd thats unexpected

#

Why didn't they just take a screenshot?

#

Wait I just realized...the name of the person and values in the question are different so it might just be a different question
