What is 4(x + 1) = 8.

Westkost [7]

$\bf{4(x+1)=8}$

Divide both sides by 4.

$\bf{x+1=\dfrac{8}{4} }$

Divide 8 by 4 to get 2.

$\bf{x+1=2}$

Subtract 1 from both sides.

$\bf{x=2-1 }$

Subtract 1 from 2 to get 1.

$\bf{x=1 \ \ \to \ \ \ Answer}$

<h2>Verification</h2>

Let x=1.

7*4 8*4 5*4 20*4

28 32 20 80

There are 28 dolls, 32 balls, 20 cars for 80 total toys
