Answer:
Solution for 7x-3=9x+5 equation:
x = -4
Explanation:
Simplifying
7x + -3 = 9x + 5
Reorder the terms:
-3 + 7x = 9x + 5
Reorder the terms:
-3 + 7x = 5 + 9x
Solving
-3 + 7x = 5 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
-3 + 7x + -9x = 5 + 9x + -9x
Combine like terms: 7x + -9x = -2x
-3 + -2x = 5 + 9x + -9x
Combine like terms: 9x + -9x = 0
-3 + -2x = 5 + 0
-3 + -2x = 5
Add '3' to each side of the equation.
-3 + 3 + -2x = 5 + 3
Combine like terms: -3 + 3 = 0
0 + -2x = 5 + 3
-2x = 5 + 3
Combine like terms: 5 + 3 = 8
-2x = 8
Divide each side by '-2'.
x = -4
Simplifying
x = -4
