8t^2 - 11t - 4
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
12 + x = 6x + 2; subtract 2 from both sides 10 + x. = 6x;; subtract x from both sides 10 = 5x; divide both sides by 5 2 = x; x = 2

the answer is simply 2 because 10+-3 is 7+-4 is 2 you just subtract negatives from the positives
First subtract 4-2, which equals 2. Then add 2+8=10.
You can first subtract 2 from 12 to get 10. Then when you bring 10 across the = sign, it becomes -10, so 42-10 is 32.
34 to the 2 power subtract 25 is 1,131
92,054,000 is the answer.
1 000 000 + 500 000 + 50 000 + 200 + 60 + 5 OR 10 to the power 6 plus 5 x 10 to the power 5 plus 2 x 10 to the power 4 plus 2 x 10 to the power 2 plus 6 x 10 plus 5
Subtract: 2x = -20Divide by 2: x = -10
You need to be very careful. In this example, 2^4 + 2^4 = 2 * 2^4 = 2^5 (where the ^ symbol means to the power of, and * means multiplied by.
