Answer:

2

Explanation:

Simplifying the Algebraic Equation.

( 5x - 7 ) -5 (7x - 12 ) + 7 = 0

Removing brackets.

5x - 7 - 35x + 60 + 7 = 0

Combining like terms.

5x - 35x + 60 + 7 - 7 = 0

- 30x + 60 = 0

- 30x = - 60

dividing bothsides by - 30


( - 30x)/( - 30) = ( - 60)/( - 30) \\ \\ x \: = 2

Answer:

x = 2

Explanation:

Simplifying expressions:

5x - 7 - 5(7x - 12) + 7 = 0

Distribute (-5) to each term of (7x - 12)

5x - 7 + 7x*(-5) + (-12)*(-5) + 7 = 0

5x - 7 - 35x + 60 + 7 = 0

5x - 35x - 7 + 60 +7 = 0

Combine like terms.

-30x + 60 = 0

Subtract 60 from both sides

-30x = -60

Divide both sides by (-30)

x = (-60)/(-30)

x = 2
