Answer 2

Answer:

The number is 18.

Adding 8 to 4 times 18 you get 80.

Step-by-step explanation:

Step 1 of 2:

Set up the equation for "Add 8 to 4 times a number you get 80".

Let the unknown number be $x$.

The mathematical expression for verbal description is,

$4x+8=80$

Step 2 of 2:

Now solve for $x$.

$4x+8=80\\4x=80-8\\4x=72$

Divide both sides of the equation by 4.

$\frac{4x}{4} =\frac{72}{4} \\x=18$

Hence the number is 18.

Verify:

Substitute $x=18$ in $4x+8=80$ and check.

$4(18)+8=80\\\\72+8=80\\80=80$

LHS = RHS
