Question

we just subtracted 6 from both sides of the hanger diagram. show that we can subtract 6 from both sides of the equation, too.
2(x + 3) = 18
2x + 6 = 18

diagram with shapes and a total of 18, two purple squares (x), two orange pentagons (x), and a purple rectangle with a purple square (x) and a ? part, labeled 18

Explanation:

Step1: Analyze the equation

We have the equation \(2x + 6=18\). To isolate the term with \(x\), we need to subtract 6 from both sides.

Step2: Subtract 6 from both sides

Subtract 6 from the left side: \(2x + 6-6 = 2x\).
Subtract 6 from the right side: \(18 - 6=12\).
So the blanks should be filled with 6 and 6 (since we subtract 6 from both sides).

Answer:

The first blank (above the subtraction sign on the left) is 6, and the second blank (above the subtraction sign on the right) is 6.
