Find the value of x and y 8y−3x+7=02x−y+4=0
If 5x-2y=17 and 3x+y=8, then find the value of x and y
Simplify:
(i)(7x−8)(3x+2)(ii)(px−q)(px+q)(iii)(5a+5b−c)(2b−3c)(iv)(4x−5y)(5x−4y)(v)(3y+4z)(3y−4z)+(2y+7z)(y+z)
If 5x−4y=7 and xy=8, find : 125x3−64y3
If x : y = 4 : 7, Find the value of (3x+ 2y) : (5x + y).
