Length of rectangle: 4x+3
Perimeter of rectangle: 12x+10
Solving:
4x+3 + 4x+3= 8x+6
Now we have 8x+6 but, we still need our width.
12x+10 - 8x+6 = 4x+4
So now, since we only have 4x+4 left for our width, we are going to divide that by 2 because in a rectangle, there are 2 lengths and 2 widths.
So in conclusion, the width of the rectangle is 2x+2
Glad I could help!
