Question

45-X=4X +25=

Answer 1

Simplifying 45 + -1X = 4X + 25 Reorder the terms: 45 + -1X = 25 + 4X Solving 45 + -1X = 25 + 4X Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-4X' to each side of the equation. 45 + -1X + -4X = 25 + 4X + -4X Combine like terms: -1X + -4X = -5X 45 + -5X = 25 + 4X + -4X Combine like terms: 4X + -4X = 0 45 + -5X = 25 + 0 45 + -5X = 25 Add '-45' to each side of the equation. 45 + -45 + -5X = 25 + -45 Combine like terms: 45 + -45 = 0 0 + -5X = 25 + -45 -5X = 25 + -45 Combine like terms: 25 + -45 = -20 -5X = -20 Divide each side by '-5'. X = 4 Simplifying X = 4

Answer 2

X=4
You can find this out by 
1.Simplify both sides of the equation.
2.Simplify that
3.Subtract 4x from both sides.
4.Subtract 45 from both sides.
5.Divide both sides by -5.
45-4=41
So yes
and 4*4+25=41
So yes, x=4
