What values should a and b have so that the next system of equations has an infinite amount of solutions? ax - 7y = -188x - by = -9a

for the system to have an infinite amount of solutions, the equations must be equal

Ax - 7y = -18            

8x - By = -9A    

a/8 = -7/-b   = -18/-9a

a/8 = 7/b =2/a

using cross products

a^2 = 16

a =4

then

4/8 = 7/b

4b = 56

b = 56/4 = 14

a negative exponent is translated as follows:

so, we have

25.2

step-by-step explanation:

2+4x6-8/10= 25.2
