8 3{x - 2[x 5(x 3)]}i dont know if it is 8^3 or 83 or 8x3 but it is the last to multiplied then i can just adjust the answer acordingly
first muliply the most inner term8 3{x - 2[x 5(x 3)]}= 8 3{x - 2[x 8]}8 3{x 9- 2x 8}
if it is 8^3 = 512
8 3{x 9- 2x 8}= 512{x 9- 2x 8}= 512x 9- 1024x 8}

PLEASE HELP ME ASAP!
TEA [102]

Answer:

x=5, y=2

Step-by-step explanation:

You simply write down what you see:

3x - 4y + 4x - 5y = 17

2x - 3y + 3x - 5y = 9

Then you simplify by grouping the x and the y terms:

7x - 9y = 17

5x - 8y = 9

Now you want to get equal amounts of x or y. Let's go for x. If we multiply the top eq with 5 and the bottom one with -7, we get:

35x - 45y = 85

-35x  + 56y = -63

-------------------------+ now we can add them:

11y = 22 divide by -11

y = 2

So 7x - 18 = 17, x =5

Finally, it makes sense to double check by filling in these answers in the original equations, just to see if no mistakes were made:

3*5 - 4*2 = 7

4*5 - 5*2 = 10

7+10 = 17: ok!

2*5 - 3*2 = 4

3*5 - 5*2 = 5

4+5 = 9: ok!
