Answer:
x = - 39/148
y = -6/37
Step-by-step explanation:
substitute the given value of y into the equation to get 8x-13 (12x+3)=0
solve for x to get x= - 39/148
substitute the given value of x into 12x+3=y
12 x (-39/148) + 3 = y
-6/37 = y
(t + 8) (-2) = 12
Distributive property >>> -2t + -16 = 12
Inverse operation >>>> -2t + -16+16 = 12+16
Simplify >>>> -2t = 28
Divide >>>> -2t/-2 = 28/-2
Final answer >>>> t = -14

Step-by-step explanation:
65x+105=y
Substitute 6 for x to find the cost for 6 classes
65(6)+105=y
390+105=y
495=y
