Question

When solving the equation − 1 2 ( x + 10 ) = − 3 − 2 1 ​ (x+10)=−3, identify the operation that should be done first. ( 1 point

Answer 1

To solve the equation − 1/2(x + 10) = −3, the operation that should be done first is the distributive property. Then, isolate the variable and solve for x. Thus, the solution to the equation is x = -4.

Step-by-step explanation:

When solving the equation − 1/2(x + 10) = −3, the operation that should be done first is the distributive property. This involves multiplying the -1/2 to both terms inside the parentheses, which gives us -1/2 * x and -1/2 * 10.

To simplify, we have -1/2x - 5 = -3. The next step would be to isolate the variable x. We can do this by adding 5 to both sides of the equation.

After adding 5, we have -1/2x = 2. Finally, we can multiply both sides of the equation by -2 to eliminate the fraction and solve for x.

Thus, the solution to the equation is x = -4.
