Solve for x. 45(15x+20)−7x=56(12x−24)+6

Nady [450]

Answer:

The value of the equation for x is $x=\frac{1119}{2}$ or 559.5.

Step-by-step explanation:

Consider the provided equation.

$45(15x+20)-7x=56(12x-24)+6$

We need to solve the equation for x.

Use the distributive property: $a(b+c)=ab+ac$

$45(15x+20)-7x=56(12x-24)+6$

$675x+900-7x=672x-1344+6$

Add the like terms.

$668x+900=672x-1338$

Isolate the variable as shown:

$672x-668x=900+1338$

$4x=2238$

$x=\frac{2238}{4}$

$x=\frac{1119}{2}$

Hence, the value of the equation for x is $x=\frac{1119}{2}$ or 559.5.
