Question

What is 2(x+3)=x-4 (working out shown)

Answer 1

Equation step-by-step:

2(x + 3) = x - 4 → we use the distributive property

2x + 6 = x - 4 → we take + 6 to the right side of the equation

2x = x - 4 - 6 → we solve for - 4 - 6

2x = x - 10 → we take x to the left side of the equation

2x - x = - 10 → we solve for 2x - x

x = - 10 → final answer

Answer 2

2(x+3)=x-4 is our original equation and we want it solved for x. Order of operations, or PEMDAS, tells us to work with the parentheses on the left first.

2(x + 3) = x - 4

2x + 6 = x - 4        <-------multiply by 2 on the left side, for both terms

2x = x - 10            <--------subtract 6 on both sides

x = -10                 <--------subtract x on both sides

Thus x = -10
