Rewrite the expression using GCF and distributive property. 64x-24

Ede4ka [16]

The greatest common factor between 64 and 24 is 8

Let's divide both terms in the expression by 8 and leave the expression in parenthesis...

Like this!

64x -24

$\frac{64x}{8} - \frac{24}{8}$

8x - 3

Leave 8 we divided outside the parenthesis

Now we have this!

8( 8x - 3)

This is the distributive property form!

511 = -7 (10x – 13) steps

PilotLPTM [1.2K]

Answer: $x=-6$

Simplify both sides of the equation

$511=(-7)(10x)+(-7)(-13)(Distribute)\\511=-70x+91$

Flip the equation

$-70x+91=511$

Subtract 91 from both sides

$-70x+91-91=511-91\\-70x=420$

Divide both sides by -70

$-70x/70=420/-70\\x=-6$
