To solve this system [x*7% = y], [x+y = 55], first solve for y in the second equation: y = 55-x. Then, substitute y in the first equation for 55-x: x*7%=55-x. Since x*7% is 1.07x, we can say that: 1.07x = 55-x. Then, add x to both sides to get: 2.07x = 55. Divide by 2.07, and x = 25.57. Finally substitute 25.57 for x in the second equation to get: 25.57+y = 55 , and y = 24.43.
Therefore, x = 25.57, and y = 24.43
