Question

3x+2(x+2)=20-(2x-5)
​

Answer 1

Answer:

If $3x+2(x+2)=20-(2x-5)$ then $x = 3$

Step-by-step explanation:

$3x+2(x+2)=20-(2x-5)$

$3x + 2x + 4 = 20 - 2x + 5$

$5x + 4 = 25 - 2x$

$5x + 2x = 25 - 4$

$7x = 21$

$x = 21/7$

$x = 3$

Answer 2

Given: $3x+2(x+2)=20-(2x-5)$

We have to solve the above equation.

• By using the Bodmas rule, we are solving the above equation.
• As we know that the Bodmas rule is used to remember the order of operations to be followed while solving expressions in mathematics.

Where,

$\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

We are solving in the following way:

We have,

$3x+2(x+2)=20-(2x-5)$

$\begin{array}{l}\Rightarrow 3 x+2(x+2)=20-(2 x-5) \\\Rightarrow 3 x+2 x+4=20-(2 x-5)\end{array}$

$\begin{array}{l}\Rightarrow 3 x+2 x+4=20-(2 x-5) \\\Rightarrow 5 x+4=20-(2 x-5)\end{array}$

$\begin{array}{l}\Rightarrow 5 x+4=20-(2 x-5) \\\Rightarrow 5 x+4=20-2 x+5\end{array}$

$\begin{array}{l}\Rightarrow 5 x+4=20-2 x+5 \\\Rightarrow 5 x+4=25-2 x\end{array}$

$\Rightarrow 5x+2x=25-4\\\\\Rightarrow7x=21\\\\\Rightarrow x=\frac{21}{7}$

Solving the above equation further we get,

$x=3$

Hence, the solution of the above equation is$3$.
