-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
WOuldn't it be 4b-8
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
-3b=96+b -4b=96 b=-24
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
4b
5b = 8 therefore b = 8/5 therefore b = 1.6
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
WOuldn't it be 4b-8
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
-3b=96+b -4b=96 b=-24
-86
It is a linear equation in one variable, b. 4b + 8/-2 = 10 4b - 4 = 10 4b = 14 b = 14/4 = 3.5
That depends what the values of k and b are.
