The equation cannot be solved as there are two unknowns. However it can be simplified and the two unknowns (a and b) expressed in terms of the second unknown.
1) Expressing a in terms of b
4a + 2 = 3b - 5
4a = 3b -7 if desired this could be stated as a = (3b - 7)/4
2) Expressing b in terms of a
3b - 5 = 4a + 2
3b = 4a + 7 if desired this could be stated as b = (4a + 7)/3

They appear to be the equations of two parallel lines in the a-b plane.
5a or 4a squared
As written, that equals 32a - 8, which factors to 8(4a - 1) If you meant 20a^2 + 12a - 8, that factors to 4(5a - 2)(a + 1)
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.

4a + 2 = Answer let a = 2 then Answer equals 4(2) + 2 = 8 + 2 = 10.
4a + 2 = 4(6) + 2 = 24 + 2 = 26
a= -4
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
9a + 4a = 26 13a = 26 a = 26/13 a = 2
It is an equation in the single unknown variable, a. a = -4
so 5a = -20 making a = -4

a-16 = a/4+2 Multiply all terms by 4: 4a-64 = a+8 4a-a = 8+64 3a = 72 a = 24
They appear to be the equations of two parallel lines in the a-b plane.
a = -2-4a/3-2 = 8-4a = 8(3-2) times both sides by (3-2)-4a = 24-16-4a = 8-a = 2 divide both sides by 4a = -2 times both sides by -1
