why does x=25 in equation 0.1(x+10)=0.3+-4?

Question

in the last part of the steps -5/-0.2 does not equal 25

i have to divide each side by -0.2 to get x by itself

Answer 1

In the equation 0.1(x+10)=0.3+-4, x does not equal to 25. The problem is worked out below:

Given the equation:  0.1(x+10)=0.3+-4

Multiply 0.1 times x and 0.1 times 10 to get:  0.1x+1=0.3+-4

Subtract the 1 from both sides to get:  0.1x=0.3+-4-1

Simplify the right side of the equation to get:  0.1x=-4.7

Divide both sides by 0.1 to get:  x=-47

Answer 2

x doesn't = 25 or 47.

x =33

plug it into the equation

.1(x+10) = .3 + 4

.1(33+10) = 4.3

43(.10) = 4.3

try 47

.1(47+10) = 4.3

5.7 doesn't = 4.3

try 25

.1(25+10) =4.3

3.5 doesn't = 4.3
