Answer:
x = 2.
Step-by-step explanation:
"7x - 5 = 2x
⇒ 7x - 2x = 5
⇒ 5x = 5
⇒ x = 5/5 = 1
Simplifying
7x + -5 = 2x + 5
Reorder the terms:
-5 + 7x = 2x + 5
Reorder the terms:
-5 + 7x = 5 + 2x
Solving
-5 + 7x = 5 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-5 + 7x + -2x = 5 + 2x + -2x
Combine like terms: 7x + -2x = 5x
-5 + 5x = 5 + 2x + -2x
Combine like terms: 2x + -2x = 0
-5 + 5x = 5 + 0
-5 + 5x = 5
Add '5' to each side of the equation.
-5 + 5 + 5x = 5 + 5
Combine like terms: -5 + 5 = 0
0 + 5x = 5 + 5
5x = 5 + 5
Combine like terms: 5 + 5 = 10
5x = 10
Divide each side by '5'.
x = 2
Simplifying
x = 2
