Answer:

Solution for 7x-3=9x+5 equation:

x = -4

Step-by-step 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
