Question

Solve the following equation and check your result in each case maths question 5(2x-3) -3(3x -7 ) =5

Answer 1

Answer:

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

10x-13-9x+14=5

x+1=5

x=5-1

x=4

Answer 2

AnswEr :-

• Value of x is -1.

Given :-

• 5 (2x - 3) - 3 (3x - 7) = 5

To Find :-

• Value of x

SoluTion :-

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

→ 10x - 15 - 9x + 21 = 5

[ re arrange the like terms ]

→ 10x - 9x - 15 + 21 = 5

→ x + 6 = 5

→ x = 5 - 6 [ taking 6 to RHS ]

→ x = - 1

★Verification★ :-

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

Put the value of x in the equation

5 { 2(-1) - 3 } - 3 { 3(-1) - 7 } = 5

→ 5 { - 2 - 3 } - 3 { - 3 - 7 } = 5

→ 5 { - 5 } - 3 { - 10 } = 5

→ - 25 + 30 = 5

→ 5 = 5

Hence, Verified.
