Question

4x + 7 - 5x (x + y- 9)​

Answer 1

Step-by-step explanation:

• 4x + 7 - 5x(x + y - 9)
• 4x+7-5x²-5xy+45x
• -5x²+49x-5xy+7

Answer 2

To solve : $4x+ 7 -5x (x + y -9 )$

Solution :

• To solve the above equation we will follow BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

• where,  

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

• According to above rule we will solve .

• $4x+ 7 -5x (x + y -9 )$  

        $4x + 7 - 5x^{2} - 5xy+45x$

Hence , on solving $4x+ 7 -5x (x + y -9 )$  we get , $4x + 7 - 5x^{2} - 5xy+45x$  .
