X =​

Answer 1

Answer:

X= 9

Step-by-step explanation:

4×2x + 4×7 = 15×x - 15×7

8x + 28 = 15x - 105

8x -15x = -105-28

-7x = -133

X = -133 ÷ -7

X= -133/-7

X= 9

Answer 2

Answer:

X=19

Step-by-step explanation:

4(2x+7)=15(x-7)

8x+28=15x-105

8x-15x = - 105-28

-7x= - 133 ( - ve signs will cancel out)

7x=133

x=133/7

x= 19

Verification :

4(2*19+7)=15(19-7)

4(45)=15(12)

180=180

Hence, Verified.
