Answer:
We simplify the equation to the form, which is simple to understand
5x+25=10
We move all terms containing x to the left and all other terms to the right.
+5x=+10-25
We simplify left and right side of the equation.
+5x=-15
or this is another way
Simplifying
5x = 25 + -10
Combine like terms: 25 + -10 = 15
5x = 15
Solving
5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = 3
Simplifying
x = 3
We divide both sides of the equation by 5 to get x.
x=-3
