Question

solve each of the following equations and check your answer in each case : 7-2(5-3x)=4(x-3)+5​

Answer 1

Answer:

x = -2

Step-by-step explanation:

7-2(5-3x) = 4(x-3) + 5

=> 7 - 10 + 6x = 4x - 12 + 5

=> 6x -3 = 4x - 7

=> 6x - 4x = 3-7

=> 2x = (-4)

=> x = (-4)/2

=> x = -2

Answer 2

Answer:

7 - 2 (5 - 3x) = 4 (x-3) + 5

7 - 10 + 6x = 4x - 12 + 5

-3 + 6x = 4x -7

- 3 + 6x - 4x + 7 = 0

4 + 2x = 0

2x = - 4

x = -4 / 2

x = -2

Substitute and check

7 - 2 ( 5 - 3 (-2) ) = 4 ( -2 -3 ) + 5

7 - 10 - 12 = - 20 + 5

- 15 = -15

Hence, proved that the value of x is - 2
