Question

solve the folowing equations.check your result in each case 2(x-3)-3(3x-7)=5​

Answer 1

Step-by-step explanation:

The above question can be written as,= 10x – 15 – 9x + 21 = 5

Now, find the value of x by considering the given equation,

= 10x – 15 – 9x + 21 = 5

= x + 6 = 5

Transposing 6 to RHS and it becomes -6

= x = 5 – 6

= x = -1

By substituting -1 in the place of x in given equation, we get

LHS,

= 10 (-1) -15 -9(-1) + 21

= -10 – 15 + 9 + 21

= -25 + 30

= 5

By comparing LHS and RHS

= 5 = 5

∴ LHS = RHS

Hence, the result is verified.

Solution

Solution

5(2x−3)−3(3x−7)=5

⇒10x−15−9x+21=5
