Question

8. 5(2x - 3)-3(3.x - 7) = 5
= 5 solve and check​

Answer 1

Step-by-step explanation:

5(2x - 3)-3(3.x - 7) = 5

10x – 15 – 9x + 21 = 5

= x + 6 = 5

Transposing 6 to RHS and it becomes -6

= x = 5 – 6

=x=-1

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

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

=-10– 15 + 9 + 21

= -25 + 30

= 5

Hence, the result is correct
