Yes that is correct
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
This is the same as: 13-2b = 21 -2b = 21-13 -2b = 8 b = -4
4m - 8 = 6m =>4m - 6m = 8 => -2m = 8 => m = -(8/2) => m = -4
it is equal to +x
-8 - (-13) = - 8 + 13 = +5 ( minus a minus is a plus)
Since 8 does not equal 13 - 4the equation (8 = 13 - 4) is false and so (8 = 13 - 4) = 0
8 plus 1 times 12 minus 13 is equal to seven.
(-5)-8=.............(-5)+(-8)=............-13(Negitive Thirteen)
43/4 - 13/8 = 46/8 - 13/8 = 33/8
-5 - 13 = -18
21
-18
-8
-13 - 8 = -21
12.5
It is 13/72 minus 3/8 = -7/36
