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

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
