Hello, My Dear Friend!

Solution for 4(5x-3)=48 equation:

<span>Simplifying:
</span>4(5x + -3) = 48<span>

</span><span>Reorder the terms:
</span>4(-3 + 5x) = 48
(-3 * 4 + 5x * 4) = 48
(-12 + 20x) = 48<span>

</span><span>Solving:
</span>-12 + 20x = 48<span>

</span><span>Solving for variable 'x'.
</span>Move all terms containing x to the left, all other terms to the right.
<span>Add '12' to each side of the equation.
</span>-12 + 12 + 20x = 48 + 12<span>

</span>Combine like terms: -12 + 12 = 00 + 20x = 48 + 12
20x = 48 + 12<span>

</span><span>Combine like terms: </span>48 + 12 = 60
20x = 60<span>

</span><span>Divide each side by '20'.
</span>x = 3<span>

</span><span>Simplifying:
</span>x = 3<span>

Therefore, THAT is The Answer!^^^ 

</span>=====> x = 3 <=====
