Answer:-2
Step-by-step explanation:
7x + 5 = 5x + 1
Reorder the terms:
5 + 7x = 1 + 5x
Solving
5 + 7x = 1 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
5 + 7x + -5x = 1 + 5x + -5x
Combine like terms: 7x + -5x = 2x
5 + 2x = 1 + 5x + -5x
Combine like terms: 5x + -5x = 0
5 + 2x = 1 + 0
5 + 2x = 1
Add '-5' to each side of the equation.
5 + -5 + 2x = 1 + -5
Combine like terms: 5 + -5 = 0
0 + 2x = 1 + -5
2x = 1 + -5 5 + 7x = 5x + 1
Combine like terms: 1 + -5 = -4
2x = -4
Divide each side by '2'.
x = -2
Simplifying
x = -2
Step-by-step explanation:
A.T.Q-
=> 7x-5 = 5x+1
=> 7x-5x = 1+5
=> 2x = 6
=> x = 6/2
=> x = 3
Therefore, the value of 'X' is 3, for which the expression (7x-5) and (5x+1) becomes equal
