Solution for 3[4(0.25+0.5z)-0.75z]=3[8(0.50+0.25z)] equation:


Simplifying
3[4(0.25 + 0.5z) + -0.75z] = 3[8(0.50 + 0.25z)]
3[(0.25 * 4 + 0.5z * 4) + -0.75z] = 3[8(0.50 + 0.25z)]
3[(1 + 2z) + -0.75z] = 3[8(0.50 + 0.25z)]

Combine like terms: 2z + -0.75z = 1.25z
3[1 + 1.25z] = 3[8(0.50 + 0.25z)]
[1 * 3 + 1.25z * 3] = 3[8(0.50 + 0.25z)]
[3 + 3.75z] = 3[8(0.50 + 0.25z)]
3 + 3.75z = 3[(0.50 * 8 + 0.25z * 8)]
3 + 3.75z = 3[(4 + 2z)]
3 + 3.75z = [4 * 3 + 2z * 3]
3 + 3.75z = [12 + 6z]

Solving
3 + 3.75z = 12 + 6z

Solving for variable 'z'.

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

Add '-6z' to each side of the equation.
3 + 3.75z + -6z = 12 + 6z + -6z

Combine like terms: 3.75z + -6z = -2.25z
3 + -2.25z = 12 + 6z + -6z

Combine like terms: 6z + -6z = 0
3 + -2.25z = 12 + 0
3 + -2.25z = 12
