Question

ПРИ КАКОМ ЗНАЧЕНИИ Х РАЗНОСТЬ ВЫРАЖЕНИЙ 0,1Х+4 И 0,5Х-2 РАВНА 5 ?

Answer 1

(0.1x+4)-(0.5x-2)=5
0.1x+4-0.5x+2=5
4+2-5=0.5x-0.1x
0.4x=1
x=2.5

Answer 2

Solving the Equation for the Value of X

To solve for the value of x in the given equation 0.1x + 4 = 0.5x - 2, we can use algebraic methods to isolate x on one side of the equation.

First, let's subtract 0.1x from both sides of the equation to get rid of it from the left side: 4 = 0.5x - 0.1x - 2

This simplifies to: 4 = 0.4x - 2

Next, let's add 2 to both sides of the equation to isolate 0.4x: 4 + 2 = 0.4x 6 = 0.4x

Now, we can solve for x by dividing both sides by 0.4: x = 6 / 0.4 x = 15

So, the value of x that satisfies the equation 0.1x + 4 = 0.5x - 2 is 15.

This solution is derived from the algebraic manipulation of the given equation.

Therefore, the value of x that satisfies the equation 0.1x + 4 = 0.5x - 2 is 15.
