It is a linear equation in two unknown variables, a and b. It can be simplified (slightly) but cannot be solved becasue to solve with two unknowns you need two independent equations.
Incidentally,
a + 5 = (a - 7) + 12 = (3b + 2) +12 = 3b +14

3b - 2 equals 7b plus 4?
3b -2 =7 b+4
3b-2 equals 7b plus 4?
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
How do you factor 49x2 plus 42xb plus 9b2?
(3b + 7x)(3b + 7x) or (3b + 7x)2
What is 26 equals 3b-2-7b?
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
What is the ordered pair of a equals 3b - 4 and a plus b equals 16?
Write down both equations (I'll label them (1) and (2)):(1) a = 3b - 4(2) a + b = 16Pass b to the left side of the equation (1):(1) a - 3b = -4(2) a + b = 16Multiply (1) by -1:(1) -a + 3b = 4(2) a + b = 16Add down both equations:-a + 3b + a + b = 4 + 164b = 20b = 5Replace b in (2):a + 5 = 16a = 11
3b - 2 equals 7b plus 4?
3b -2 =7 b+4
What is the answer to 3b plus 6 equals 12?
3b + 6 = 12 3b = 6 b = 2
-2b plus 7-3b equals 2?
-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
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
Does a plus b plus 2 plus 3 equals 2a plus 3b?
a+b+2+3=5+a+b
What is 20 plus 3b when b equals -6?
20+3b = 20 + 3(-6) = 20-18 = 2
How do you solve 3b plus 2a equals 2 and -2 plus a equals 8?
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.
What is 2a plus 3b equals 6ab?
With the assumption your asking what a or b are in terms of each other. a=3b/(6b-2) b=2a/(6a-2)
3b-2 equals 7b plus 4?
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
How do you factor 49x2 plus 42xb plus 9b2?
(3b + 7x)(3b + 7x) or (3b + 7x)2
What is 26 equals 3b-2-7b?
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
What is the ordered pair of a equals 3b - 4 and a plus b equals 16?
Write down both equations (I'll label them (1) and (2)):(1) a = 3b - 4(2) a + b = 16Pass b to the left side of the equation (1):(1) a - 3b = -4(2) a + b = 16Multiply (1) by -1:(1) -a + 3b = 4(2) a + b = 16Add down both equations:-a + 3b + a + b = 4 + 164b = 20b = 5Replace b in (2):a + 5 = 16a = 11
