Answer:
I think the answer is 6x + 3 = 7x + -3. If you want to find out what x is, then x is 6.
Step-by-step explanation:
Look at the key, the white cube represents 1 and the gray cube represents -1. So first look at the left. You see 6 rectangles labeled x, right? That represents 6x, next to the 6 rectangles, you see 3 white cubes which represents 3 because since one white cube equals 1, there are 3 of them so you do 1+1+1, which is 3. Same for the right side. You see 7 rectangles on the right, right? That represents 7x, and you see the gray cubes next the the rectangles? That represents -3, becuase one gray cube represents -1, so since there are 3 gray cubes, you do -1 + -1 + -1 which equals to -3. Now this brings you to the equation, 6x + 3 = 7x + -3.
If you want to find what x is, subtract 3 from both sides -3-3=-6 and 3-3, and 3-3 cancels out because it equals to 0. Then you subtract 7 from both sides, 6-7 = -1; 7-7 cancels out. Now it leaves you to -1x = -6, do inverse operatio; -6 divided by -1 which gives u, x = 6. I hope this helps! Pls mark brainest!
