-4 - 6 - (-10) = 0
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
6 miles minus 4 miles = 2 miles 10 yd minus 4 yd = 6 yd So answer: 2 miles 6 yards.

5 x 6 - 9 - 4 = 17
If we read this carefully, what you're asking for is (4 of something) minus (1 of the same thing). The result is 3 of them . . . 3 radical 6.
4 x2
4 radical 6
-4 - 6 - (-10) = 0
Either answer is correct, depending on the parentheses that should have been specified. sqrt(6*4) = sqrt(24) sqrt(6)*4 = 4*sqrt(6)
6√5 + 2√5 - 7 = 8√5 - 7, which cannot be simplified.
positive 6 minus positive 4 = (+6) - (+4)= +2
2 sqrt(6) - 5 sqrt(24) = 2 sqrt(6) - 5 sqrt(4 x 6) = 2 sqrt(6) - 5 sqrt(4) sqrt(6) =2 sqrt(6) - 5 x 2 sqrt(6) = 2 sqrt(6) - 10 sqrt(6) =-8 sqrt(6)
6 4--2=6
2√20 - 3√7 - 2√5 + 4√63 = 2√(4 x 5) - 3√7 - 2√5 + 4√(9 x 7) = 4√5 - 2√5 - 3√7 + 12√7 = 2√5 + 9√7
First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
Start by finding a common denominator. If the radical includes the entire fraction (3/4 for the first part), the common denominator would be square root of 12.
