Question

Resolva a equação matrical:


[-1 4 5] [3 5 2] [2 7. 2]
[0 2 7] + [-1 5 3] = x+[8 -1-3]
[1 -1 -2] [4 2 2] [-1. 9 5]​

Answer 1

14535227.2027+-153=x+8-1-31-1-2422-1.95

We move all terms to the left:

-14535227.2027+-153-(x+8-1-31-1-2422-1.95)=0

We add all the numbers together, and all the variables

-(x-2448.95)-14535227.2027-153+=0

We add all the numbers together, and all the variables

-(x-2448.95)=0

We get rid of parentheses

-x+2448.95=0

We add all the numbers together, and all the variables

-1x+2448.95=0

We move all terms containing x to the left, all other terms to the right

-x=-2448.95

x=-2448.95/-1

x=2448+0.94999999999982/1
