To find the two numbers that add up to 90, we can set up an equation as x + y = 90. Since we have two unknowns, we need another equation to solve for both variables. Without additional information or constraints, there are infinitely many pairs of numbers that could satisfy this equation, such as 50 and 40, 60 and 30, or even fractions like 45.5 and 44.5.
90 + 90 + 60 = 240

90 minus 75 =15 therefore 15 + 75 = 90
54 + 560 + 90 = 704
6 + 90 = 96
