Which matrix represents the solution to the system of equations below? 2a+b+c=2
-a+b-C=-4
a-2b+2c= 6

answer:     true

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
