Question

3(5x + 7) + 5(2x + 11) = 3(8x - 5) - 6(7x - 4)

Answer 1

To find : value of $x$

Given : $3 ( 5x + 7) + 5(2x + 11) = 3(8x - 5) - 6 ( 7x - 4)$

Solution :

• To find the value of $x$ , we take constants at RHS leaving variable at LHS.

• By performing simple operations we find the value of $x$.
• $3 ( 5x + 7) + 5(2x + 11) = 3(8x - 5) - 6 ( 7x - 4)$

       $15x +21 +10x + 55 = 24x - 15 -42x +24 \\25x + 76 = 9 - 18x\\25x + 18x = 9 - 76 \\43x = -67 \\ x = \frac{-67}{43} \\x = -1.558$

Hence, value of $x$ is $-1.558$.

Answer 2

Given: The equation is$3(5 x+7)+5(2 x+11)=3(8 x-5)-6(7 x-4)$.

We have to solve the above equation.

By using the Bodmas rule, we are solving the above equation.

We are solving in the following way:

We have,

The equation is$3(5 x+7)+5(2 x+11)=3(8 x-5)-6(7 x-4)$

$\begin{array}{l}=>15 x+21+10 x+55=24 x-15-42 x+24 \\=>25 x+76=9-18 x \\=>25 x+18 x=9-76 \\=>43 x=-67 \\=>x=\frac{-67}{43} \\=>x=-1.558\end{array}$

Hence, the value of '$x$' will be$-1.558$
