Hey there!

Solve the equation:

  • Answer :

x = -10 ✅

  • Explanation:

2(x + 3) = x - 4

Distributive property: A(B + C) = AB + AC

>> Substitute 2 for A , x for B and 3 for C :

2(x) + 2(3) = x - 4

2x + 6 = x - 4

>> Subtract 6 from each side :

2x + 6 - 6 = x - 4 - 6

2x = x - 10

>> Subtract x from both sides :

2x - x = x - 10 - x

x = -10

▪️Let's check our work :

2(-10 + 3) ⇔ 2(-7) ⇔ -14

-10 - 4 ⇔-14

Therefore, your answer is x = -10
