15x=13.5的解方程和检验?
展开全部
解方程:
To solve the equation 15x=13.5, we need to isolate x on one side of the equation. We can do this by dividing both sides by 15:
15x/15 = 13.5/15
Simplifying gives:
x = 0.9
Therefore, the solution to the equation 15x=13.5 is x=0.9.
检验:
To check our solution, we can substitute x=0.9 back into the original equation and see if it satisfies the equation:
15(0.9) = 13.5
Simplifying gives:
13.5 = 13.5
Since this is true, we know that our solution is correct.

15x=13.5
解:x=13.5÷15
x=0.9
检验:把x=0.9代入15x
得:左边=13.5
右边=13.5
∵左边=右边
∴x=0.9是原方程的解.
