Calculate aa and then b. is matrix multiplication comutative?
a. a = 2 0
−2 3
, b = 5
0 1

b. a = −10 1
3 7
, b = −3 2
4 −1

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
