Question

Find the value of x. 3x(5+2)=16

Answer 1

Answer:

16/21

Step-by-step explanation:

We are given the equation 3x(5 + 2) = 16.

By order of operations, let's add the two numbers in the parentheses first:

3x(5 + 2) = 16

3x(7) = 16

Now, we must multiply 3x by 7:

3x * 7 = 16

21x = 16

Divide both sides by 21:

x = 16/21

The answer is thus 16/21.

Answer 2

Answer: x=0.8

Step-by-step explanation:

Distribute

$3x*5=15x$

$3x*2=6x$

$15x+6x=21x$

$21x=16$

divide 21 on both sides

$x=0.76$

round

$x=0.8$
