City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was −3° c. what was the temperature of city a and city b on that day? your city a was 5° c, and city b was 4° c. city a was 3° c, and city b was −1° c. city a was 8° c, and city b was −3° c. city a was 5° c, and city b was −5° c.

City A = x

City B = y

1st equation: 4x-8 =3y

 2nd equation: x-2y = -3 , rewrite as x = 2y-3

replace x in eq. 1 with equation 2

4(2y-3) -8 =3y

8y-12-8=3y

8y-20 = 3y

-20 = -5y

y = -20/-5 = 4

x = 2y-3 = 2(4)-3 = 5

City A was 5° C, and City B was 4° C.
