若10.5x-10=36-3y=14+4.5x,求x和y的值若10.5x-10=36-3y=14+4.5x,求x和y的值若10.5x-10=36-3y=14+4.5x,求x和y的值10.5x-10=1

若10.5x-10=36-3y=14+4.5x,求x和y的值
若10.5x-10=36-3y=14+4.5x,求x和y的值

若10.5x-10=36-3y=14+4.5x,求x和y的值
10.5x - 10 = 14 + 4.5x
6x = 24
x = 4
10.5 * 4 - 10 = 36 - 3y
42 - 10 = 32 = 36 - 3y
3y = 4
y = 4/3
答:(x,y) = (4,4/3)

由题可知:10.5x-10=14+4.5x
x=4
将x=4代入10.5x-10=36-3y可得y=4/3

10.5x - 10 = 14 + 4.5x
6x = 24
x = 4
10.5 * 4 - 10 = 36 - 3y
42 - 10 = 32 = 36 - 3y
3y = 4
y = 4/3
