The given equation is solved to give value of x as 15.
A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The given equation is as below,
-25(x - 4) = -55(x - 10)
It can be simplified as follows,
-25(x - 4) = -55(x - 10)
=> -25x + 100 = -55x + 550
=> -25x + 55x = 550 - 100
=> 30x = 450
=> x = 15
Hence, the value of x for the given equation is 15.

Simplify both sides of the equation
-25(x-4)=-55(x-10)
(-25)(x) + (-25)(-4)=(-55)(x) + (-55) (-10)
Distribute
-25x+100=-55x+550
Add 55x to both sides
-25x+100+55x=-55x+550+55x
30x+100-100=550-100
subtract 100 from both sides
30x+100-100=550-100
30x=450
divide both sides by 30
30x/30=450/30
x= 15
The value of x is 15
I hope that's help you my friend !

Answer:
15 hours
Step-by-step explanation:
10/6 ≈ 3.7
4 * 3.7 = 14.8
-round it up-
14.8 ≈ 15
456=2(20w)+4(w^2)+2(50w)
distribute
456=40w+4w^2+100w
add like terms
456=4w^2+140w
divide everybody by 4
114=w^2+35w
subtract 114 from both sides
0=w^2+35w-114
find what 2 numbers multiply to get 114 and add to get 35 and factor
-3 and 38
0=(w-3)(w+38)
set each to zero
w-3=0
w=3
w+38=0
w=-38
false since measures in real life cannot be negative
