a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
The answer to 4a times 3b equals 1.3. You have to find the value of A and B.
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
26 = 3b - 2 - 7b 28 = -4b b = -7
3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.
If you mean 3b+9 = 12 then b equals 1
If 3b = 39 thenb = 39/3b = 13.
3b + 6 = 12 3b = 6 b = 2
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
79
If a + b = 6, what is the value of 3a + 3b?
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
If: 7+3b = 61 Then: b = 18
The answer to 4a times 3b equals 1.3. You have to find the value of A and B.
50 - 3b = 353b = 50 - 353b = 15b = 5
3b -2 =7 b+4
-3b=96+b -4b=96 b=-24
