Question

1. $3(10x - 5) = 5(6x - 3)$

Explanation:

Step1: Expand both sides

$3(10x - 5) = 30x - 15$; $5(6x - 3) = 30x - 15$

Step2: Simplify the equation

$30x - 15 = 30x - 15$

Step3: Rearrange terms

$30x - 30x = -15 + 15$

Step4: Simplify to find solution

$0 = 0$

Answer:

All real numbers are solutions (the equation is an identity).
