Question

Solve: 3x + 4 (x-1) = 10.​

Answer 1

Answer:

$\huge\boxed{\underline{\underline{\mathcal{2}}}}$

Step-by-step explanation:

$\huge\boxed{\underline{\underline{\mathsf{Given: - }}}}$

$\mathsf{3x + 4(x - 1) = 10}$

$\mathsf{Let \:solve\:}$

$\huge\underline{\underline{\boxed{\mathsf{Solution}}}}$

$\mathsf{3x + 4(x - 1) = 10} \\ \mathsf{3x + 4x - 4 = 10} \\ \mathsf{7x = 10 + 4} \\ \mathsf{7x = 14} \\ \mathsf{x = \frac{14}{7} = 2 }$

Answer 2

Answer:

By solving equation $3x + 4 (x-1) = 10$ we get $x = 2$.

Step-by-step explanation:

In context to the question asked,

We have to solve the equation,

As per data given in the question,

We have,

$3x + 4 (x-1) = 10$

Here we will use the transposition method.

Now, by using the distributive property:

=> $3x + 4 x-4 = 10$

Combining the like terms,

=> $7x - 4 = 10$

Transposing 4 on the right sides,

=> $7x = 10+4$

Add the numbers,

=> $7x = 14$

Divide both sides by 7,

=> $x = 2$

Hence, the required solution is 2.
