a= -4
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 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

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

5a or 4a squared
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
