Question 49 Linear Equations in One Variable - Exercise

(5x/(2x - 1)) = 2

We have,

(5x/(2x - 1)) = 2

By cross multiplication, we get

5x = 2 × (2x - 1)

5x = 4x – 2

Transposing 4x to LHS it becomes – 4x

5x – 4x = -2

x = -2

hello students welcome to lido today we are going to solve a question related to equation so we have provided some equation and we have to find out the value of x so find x that's the question now let's see how can we solve this so the first step is to write the given as this is 5 x divided by 2 x minus 1 is equals to 2. all these are under the bracket and this is also in the bracket now we will 5 x is equals to we will do the cross multiplication so 2 multiplied by 2 x minus 1 then we will simplify this or use the distributive property so 2 multiplied by 2 x minus 2 multiplied by 1 that is the distributive property here we will use and here we will multiply so it is 4 x minus 2 that is equals to 5x now we will bring the like terms together so 5x minus 4x is equals to minus 2. so here the answer will be 5x minus 4x it's 1x so 1x is equals to minus so x will be equals to minus 2 divided by 1 or x is equals to minus 2 simply so this way we got the answer that is x is equals to minus 2 so the final answer is x is equals to minus 2. we use the cross multiplication here cross multiplication then here we did the transposition technique transposition and this way we finally got the answer for x that is minus 2. i hope you understood this question and for any query related to this write in the comment section thank you
