Answer» n:- 1)3x = 2x + 18= 3x -2x =18= x = 18▪Putting the value of x in R.H.S and L.H.S3 × 18 = ( 2 × 18) + 18= 54 = 54R.H.S = L.H.S 2) 5x + 9 = 5 + 3x= 5x - 3x = 5-9= 2x = -4= x = -2▪Putting the value of x in R.H.S and L.H.S5 × (-2) + 9 = 5 +3 × (-2)= -10 +9 = 5 + (-6)= -1 = -1R.H.S = L.H.S 3) 4Z + 3 = 6 + 2z= 4z -2z = 6 - 3= 2z = 3= z = 3/2▪Putting the value of x in R.H.S and L.H.S= (4×3/2)+3 = 6+(2×3/2)= 6 +3 = 6 + 3 = 9 = 9R.H.S = L.H.S 4) 2y + 5/3 = 26/3 -y = 2y + y = 26/3 -5/3= 3y = 26-5/3= 3y = 21/3= 3y= 7▪Putting the value of x in R.H.S and L.H.S= 2 × 7/3 + 5/3 = 26/3 -7/3= 14/3 + 5/3 = 26/3 -7/3= 14+5/3 = 26-7/3= 19/3 = 19/3R.H.S = L.H.S 5) 3m = 5m -8/5= 3m - 5m = -8/5= -2m = -8/5= 2m × 5 = 8= 10M = 8= m = 8/10= m = 4/5▪Putting the value of x in R.H.S and L.H.S= 3×4/5 = (5×4/5) - 8/5= 12/5 = 4-8/5= 12/5 = (20-8)/5= 12/5 = 12/5R.H.S = L.H.S Hence, SOLVED! |
