Solve the simultaneous equations: 3a-2b=14 12a+9b=39

kirill [66]

Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1

Subtract 43 from 20 raised to the 7th power; then multiply by 3.

viktelen [127]

Hi there! :)

Answer:

Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: 3,839,999,871

Step-by-step explanation:

"Subtract" means to take away a number from another.

" 20 raised to the 7th power" is the same thing as 20 exponent 7: $20^{7}$

SO, you want to take away 43 from $20^{7}$ and then multiply the answer by 3:

( $20^{7}$ - 43) × 3

$20^{7} =$ 1,280,000,000

(1,280,000,000 - 43) × 3

1,280,000,000 - 43 = 1,279,999,957

1,279,999,957 × 3

1,279,999,957 × 3 = 3,839,999,871

There you go! I really hope this helped, if there's anything just let me know! :)
