Answer:

The answer is - 7/30

Step-by-step explanation:

LCM between 10 and 15 is 30 so that would be your denominator.

The subtract: 7-14 = -7 so that would be your numerator.

HOPE THIS HELPS!!! :D

Answer:

The value of x will be:

$x=-5$

Step-by-step explanation:

Given the equation

$4-2(x+7)=3(x+5)$

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

$4-2x-14=3x+15$

simplifying the equation by subtracting 14 from the L.H.S

$-10-2x=3x+15$

Subtracting 15 from both sides

$-10-2x-15=3x+15-15$

$-25-2x=3x$

combining the like terms

$-25=3x+2x$

$-25=5x$

dividing both sides of the equation by 5

$\frac{-25}{5}\:=\:\frac{5x}{5}$

$-5=x$

Therefore, the value of x will be:

$x=-5$
