Question

(ii) (7x-5)-4(2 + 5x) = 10(2 - x)​

Answer 1

Answer:

7x−5−4(2+5x)=10(2−x)

Step 1: Simplify both sides of the equation.

7x−5−4(2+5x)=10(2−x)

7x+−5+(−4)(2)+(−4)(5x)=(10)(2)+(10)(−x)

(Distribute)

7x+−5+−8+−20x=20+−10x

(7x+−20x)+(−5+−8)=−10x+20(Combine Like Terms)

−13x+−13=−10x+20

−13x−13=−10x+20

Step 2: Add 10x to both sides.

−13x−13+10x=−10x+20+10x

−3x−13=20

Step 3: Add 13 to both sides.

−3x−13+13=20+13

−3x=33

Step 4: Divide both sides by -3.

−3x

−3

33

−3

x=−11

Answer 2

Ello..✌✌

( 7 x- 5 ) - 4 ( 2 + 5 x ) = 10 ( 2 - x)

=> 7 x - 5 - 8 - 20 x = 20 - 10 x

=> 7 x - 13 - 20 x + 10 x - 20 = 0

=> - 13 x + 10 x -13 - 20 = 0

=> - 3 x - 33 = 0

=> - 3 x = 33

=> x = - 33 / 3

=> x = - 11
