If 3b = 39 then
b = 39/3
b = 13.
If ( b ) equals 4, then ( 3b ) can be calculated by substituting 4 for ( b ). Thus, ( 3b = 3 \times 4 = 12 ). Therefore, ( 3b ) is equal to 12.
If a + b = 6, what is the value of 3a + 3b?
-3b=96+b -4b=96 b=-24
If you mean 3b+9 = 12 then b equals 1
a = 11 and b = 5.
If ( b ) equals 4, then ( 3b ) can be calculated by substituting 4 for ( b ). Thus, ( 3b = 3 \times 4 = 12 ). Therefore, ( 3b ) is equal to 12.
If a + b = 6, what is the value of 3a + 3b?
-3b=96+b -4b=96 b=-24
If you mean 3b+9 = 12 then b equals 1
3b + 6 = 12 3b = 6 b = 2
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
a = 11 and b = 5.
If: 7+3b = 61 Then: b = 18
its -24.
3b -2 =7 b+4
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
