3x+5/4x+2=3x+4/4x+7
Solve this linear equation
Answered by admin @
Given : (3x + 5)/(4x + 2) = (3x + 4)/(4x + 7)
= > (4x + 7)(3x + 5) = (3x + 4)(4x + 2)
= > 12x^2 + 20x + 21x + 35 = 12x^2 + 6x + 16x + 8
= > 12x^2 + 20x + 21x - 12x^2 - 6x - 16x = 8 - 35
= > 20x + 21x - 22x = -27
= > 19x = -27
= > x = -27/19
Hope this helps!
