4x - 13 = 22 - 3x
add 3x to both sides
7x - 13 = 22
add 13 to both sides
7x = 35
divide both sides by 7
x = 5
You can use an array to find 4x13 by visually representing the multiplication as a grid. Create a rectangle with 4 rows and 13 columns, where each cell represents one unit. Counting all the cells in this array will show that there are 52 individual units, thus illustrating that 4x13 equals 52. This method helps in understanding multiplication as repeated addition.
