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 =7 b+4
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
To simplify the expression (-2b - 6 + 3b - 2), first combine the like terms. The (b) terms are (-2b + 3b), which equals (b). The constant terms are (-6 - 2), which equals (-8). Therefore, the simplified expression is (b - 8).
(3b + 7x)(3b + 7x) or (3b + 7x)2
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
3b -2 =7 b+4
3b + 6 = 12 3b = 6 b = 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
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
a+b+2+3=5+a+b
20+3b = 20 + 3(-6) = 20-18 = 2
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.
With the assumption your asking what a or b are in terms of each other. a=3b/(6b-2) b=2a/(6a-2)
If b = -1.5 then -4.5 -2 = -10.5 + 4, which is true.
To simplify the expression (-2b - 6 + 3b - 2), first combine the like terms. The (b) terms are (-2b + 3b), which equals (b). The constant terms are (-6 - 2), which equals (-8). Therefore, the simplified expression is (b - 8).
(3b + 7x)(3b + 7x) or (3b + 7x)2
3b - 7b - 2 = 26 then , -2 - 4b = 26 then , 4b = 26 then you do , -4 / 26 which equals 7
