Question

Exercise 8.2
(a) -10+x+4-5=7x-5

1 Solve the following equations and verify the answers.
(d) 2(2x - 5) = 6x + 4​

Answer 1

(a) x=1 and (b) x = -7

Step-by-step explanation:

(a) x+4-5 = 7x -5+10

x-1=7x+5

7x-x=5+1

6x=6

x=6/6

x= 1 Ans

(d) 4x-10= 6x +4

4x -6x = 4+10

-2x = 14

-x = 14/2

-x = 7

By multiply both by -1 we get

-x ×-1 = 7×-1

x = -7 Ans
