Question

What is the solution to the equation 3 (2 x + 5) = 3 x + 4 x?

A)x = 0

B)x = 4

C)x = 5

D)x = 15

Answer 1

Answer:

$x=15$

Step-by-step explanation:

Step 1: Simplifying the equation we can find the value of x.

$3(2 x+5)=3 x+4 x$

Step 2: Multiply 3 with $(2 x+5)$

$6 x+15=3 x+4 x$x

Step 3: Adding 3x with 4x, which gives the equation

$6 x+15=7 x$

Step 4: Subtracting both sides of the equation by 6x

$\begin{aligned}6 x+15-6 x &=7 x-6 x \\15 &=x\end{aligned}$

Thus, the solution to the equation $3(2 x+5)=3 x+4 x$  is  $x=15$
