3(a-1)=4(a+1.5)

Solution for 3(a-1)=4(a+1.5) equation:

Simplifying
3(a + -1) = 4(a + 1.5)

Reorder the terms:
3(-1 + a) = 4(a + 1.5)
(-1 * 3 + a * 3) = 4(a + 1.5)
(-3 + 3a) = 4(a + 1.5)

Reorder the terms:
-3 + 3a = 4(1.5 + a)
-3 + 3a = (1.5 * 4 + a * 4)

Move all terms containing a to the left, all other terms to the right.

Add '-4a' to each side of the equation.
-3 + 3a + -4a = 6 + 4a + -4a

Combine like terms: 3a + -4a = -1a
-3 + -1a = 6 + 4a + -4a

Combine like terms: 4a + -4a = 0
-3 + -1a = 6 + 0
-3 + -1a = 6

Add '3' to each side of the equation.
-3 + 3 + -1a = 6 + 3

Combine like terms: -3 + 3 = 0
0 + -1a = 6 + 3
-1a = 6 + 3

Combine like terms: 6 + 3 = 9
-1a = 9

Divide each side by '-1'.
a = -9

Simplifying
a = -9
