Question

h Solve the following system of equations.
2a – 3b + c = 10
2a – 2b – 2c = 2
a + 3b + 2c = –1

Answer 1

turn it into a matrix, transform to triangular form and find your solution

Answer 2

i got -1, 6? is that right

Answer 3

you need 3 values

Answer 4

to verify you answer plug in one of the equations the values you found for a,b, and c

Answer 5

sorry i got -1,2,3

Answer 6

doesn't seem right

Answer 7

solve these equations ( row reduction to triangular form ) => 30c=60, b-3c=-8, a+3b+2c=-1

Answer 8

gives you a =1, b=-2, and c=2
