Question

8. 3(x+2) = 6(x-5)
9. 9(x+1)-36 = 7(x-1)
10. 3(x-3)+ 4(x-8)=5(x-1)​

Answer 1

The values of the given equations are :

3(x+2) = 6(x-5) = 4

9(x+1)-36 = 7(x-1) = 10

3(x-3)+ 4(x-8)=5(x-1)​ = - 23

Step-by-step explanation:

Solving and finding values of x for all the equations given,

=> Solving the first equation,

$3(x+2)=6(x-5)\\3x+6=6x-30\\6+30=6x+3x\\36=9x\\x=4$

Hence in the 1st equation(according to the question 8th number) the value of x = 4.

=> Solving the second equation ,

$9(x+1)-36=7(x-1)\\9x+9-36=7x-7\\9x-27=7x-7\\9x-7x=27-7\\2x=20\\x=10$

Hence in the 2nd equation(according to the question 9th number) the value of x = 10.

=> Solving the third equation,

$3(x-3)+4(x-8)=5(x-1)\\3x-9+4x-32=5x-5\\7x + 41=5x-5\\7x-5x=-5-41\\2x=-46\\x=-23$

Hence in the 3rd equation (according to the question 10th number) the value of x = - 23.
