Question

Solve for x: 5x + 15 = 28 A: 43/5 B: 13/5 C: 13 D: 43

Answer 1

$\mathfrak{5x + 15 = 28}$

$\mathfrak{5x = 28-15}$

$\mathfrak{5x = 13}$

$\boxed{\mathfrak{x = \dfrac{13}{5}}}$ → option B.

$\mathbb{MIREU}$

Answer 2

Answer:

B

Step-by-step explanation:

The first thing you need to do is,

28 - 15

which is 13.

Now look at the answer choices and multiply them by 5.

It cannot be C or D because it would not fit the equation.

If anyone of them equal 13 then it is the answer.

Now lets try it.

43/5 = 8.6

13/5 = 2.6

8.6 times 5 is way to big so A is not it.

2.6 times 5 is 13.

So it is B.
