Step 4: Solve for unknown
Equa3on represented with algebra 3les from step 3
Create zero pairs by adding inverse number of 1’s unit squares to both sides of the equa3on
Divide remaining Number of 1’s unit squares on the leG side of the equa3on Equally with the x unit rectangles on the right side of the equa3on, subs3tute to find second variable
