Sagot :

Certainly! Let's solve the given equation step-by-step to find which equation is equivalent to [tex]\(4x + 3(2x - 4) = 2x\)[/tex].

1. Distribute the 3 inside the parentheses:
[tex]\[ 4x + 3 \cdot (2x - 4) = 2x \][/tex]
This becomes:
[tex]\[ 4x + 3 \cdot 2x - 3 \cdot 4 = 2x \][/tex]
Simplifying inside the parentheses:
[tex]\[ 4x + 6x - 12 = 2x \][/tex]

2. Combine like terms on the left-hand side:
[tex]\[ (4x + 6x) - 12 = 2x \][/tex]
This simplifies to:
[tex]\[ 10x - 12 = 2x \][/tex]

So, the equivalent equation to [tex]\(4x + 3(2x - 4) = 2x\)[/tex] is:
[tex]\[ 10x - 12 = 2x \][/tex]

Thus, the answer is:
[tex]\[ \boxed{10x - 12 = 2x} \][/tex]
