Question

If x=25,which equation is trueA- 4(5-x)=10B- (x-10)=100C- (x-5)=120D- 2x-15=45

If x=25, which equation is true?

A) 4(5-x)=10
B) (x-10)=100
C) (x-5)=120
D) 2x-15=45

Answer 1

After substituting x=25 into each of the equations, none of them proves to be correct. Each equation's result does not match the supposed equal value, indicating either a mistake in the question or a need for further clarification.

Step-by-step explanation:

If x=25, we need to determine which equation is true by substituting the value of x into each equation.

4(5-x)=10: Substituting x gives us 4(5-25) = 4(-20) = -80, which does not equal 10, so this is not correct.

1. (x-10)=100: Substituting x gives us (25-10) = 15, which does not equal 100, so this is not correct.
2. (x-5)=120: Substituting x gives us (25-5) = 20, which does not equal 120, so this is not correct.
3. 2x-15=45: Substituting x gives us 2(25)-15 = 50-15 = 35, which does not equal 45, so this is not correct either.

After checking all options, we find that none of the given equations result in a true statement when x=25. However, if the question implies there has been a typographical error and one of them must be true, further clarification would be needed.
