✔ 最佳答案
13^2-6!+8y=12^2+y+5169-720+8y=144+y+5
8y-y=144+5-169+720
7y=700
y=100
p.s. 6! = 6x5x4x3x2x1 = 720

8y - y = 12^2 + 5 - 13^2 +6!
7y = 84 + 6!
7y = 84 + 1*2*3*4*5*6
7y = 84 + 720
7y = 804
y = 114.857142857
7y = 84 + 6!
7y = 84 + 1*2*3*4*5*6
7y = 84 + 720
7y = 804
y = 114.857142857
參考: 8y - y = 12^2 + 5 - 13^2 +6!

13^2-6!+8y=12^2+y+5
169-720+8y=144+y+5
169-5+8y=144+720+y
164+8y=864+y
8y-y=864-164
7y=700
y=100
169-720+8y=144+y+5
169-5+8y=144+720+y
164+8y=864+y
8y-y=864-164
7y=700
y=100

Sorry, type mistake8y - y = 12^2 + 5 - 13^2 +6!7y = 144 + 5 + 169 + 6!7y = 318 + 1*2 *3 *4 *5 * 67y = 318 + 7207y = 1038y = 148.285714285
8y - y = 12^2 + 5 - 13^2 +6!
7y = 84 + 6!
7y = 84 + 1*2*3*4*5*6
7y = 84 + 720
7y = 804
