Question

Four times the sum of 8 and some number is 4. What is the number?

Answer 1

Answer:

-7

Step-by-step explanation:

Let the unknown number be x

$4(8+x)=4$

Expand

$4(8+x )\\4\times 8 = 32\\4 \tiimes x = 4x\\\\= 32+4x$

$32+4x =4$

Collect like terms and simplify

$4x =4-32\\4x = -28$

Divide both sides of the equation by 4

$\frac{4x}{4} = \frac{-28}{4}$

Simplify

$x =-7$

Answer 2

Answer:

$\Huge \boxed{\mathrm{-7}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

Let the number be x.

$4(x+8)=4$

Dividing both sides by 4,

$x+8=1$

Subtracting 8 from both sides,

$x=-7$

The number is -7.

$\rule[225]{225}{2}$
