Question

Solve.
7(2x-5)‐3(4x-7)=41 ​

Answer 1

x = 55/2 or 27.5

Explanation:

7(2x-5)-3(4x-7)= 41

14x-35-12x+21 = 41

2x - 14 = 41

2x = 41 + 14

2x = 55

x = 55/2 or 27.5

Answer 2

`7(2x - 5) - 3(4x - 7) = 41 \\`

• Now, multiply 7 with (2x - 5) and 3 with (4x - 7).

`= > 14x - 35 - 12x + 21 = 41 \\`

• Transpose -35 and 21 to the RHS.

`= > 14x - 12x = 41 + 35 - 21 \\`

• Now, do the addition and subtraction.

`2x = 55`

• Now, divide both sides by 2.

`= > (2x)/(2) = (55)/(2) \\ = > x = 27.5`

Answer:

x = 27.5
