Explicación paso a paso:

Solution for 5x+9=8x-7 equation:

Simplifying

5x + 9 = 8x + -7

Reorder the terms:

9 + 5x = 8x + -7

Reorder the terms:

9 + 5x = -7 + 8x

Solving

9 + 5x = -7 + 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

9 + 5x + -8x = -7 + 8x + -8x

Combine like terms: 5x + -8x = -3x

9 + -3x = -7 + 8x + -8x

Combine like terms: 8x + -8x = 0

9 + -3x = -7 + 0

9 + -3x = -7

Add '-9' to each side of the equation.

9 + -9 + -3x = -7 + -9

Combine like terms: 9 + -9 = 0

0 + -3x = -7 + -9

-3x = -7 + -9

Combine like terms: -7 + -9 = -16

-3x = -16

Divide each side by '-3'.

x = 5.333333333

Simplifying

x = 5.333333333
