(25 +21) * 2 = 92 25 + (21 * 2) = 67
x - 2 = 4x + 46-2 = 3x + 46-48 = 3xx = -48/3 or -16
(46 + 88)/2 = 67
The answer is 82. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.

In the standard base ten system, 2 + 2 = 4
(25 +21) * 2 = 92 25 + (21 * 2) = 67
x - 2 = 4x + 46-2 = 3x + 46-48 = 3xx = -48/3 or -16
(46 + 88)/2 = 67
The answer is 82. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
2 + 46 = 48
(46 + 88)/2 = 134/2 = 67
23 x 2 = 46
2a + 2b = 26 2b + c = 22 ===> b = 11 - c/2 4c + 2b = 46 ===> b = 23 - 2c From the 2nd and 3rd equations: 11 - c/2 = 23 - 2c 22 - c = 46 - 4c 22 - 46 = -4c + c ===> -24 = -3c ===> c = 8 Substitute c=8 into the 3rd equation: b = 23 - 16 = 7 Substitute b=7 into the 1st equation: 2a + 14 = 26 2a = 12 ===> a = 6
65+2=67 65 +2 ------ 67
