Answer:
Answer 1.)
β 4x - 15 + 2x = x +20
β 6x -15 = x +20
β 5x = 35
β x = 7
Answer 2.)
β 2(2xβ5)=20βx
β 4x - 10 = 20 - x
β 5x = 30
β x = 6
Answer 3.)
β 3β4x=10x+10
β 14x = -7
β x = -1/2
Answer 4.)
β 4(2xβ1)=β10(xβ5)
β 8x - 4 = -10x + 50
β 18x = 54
β x = 3
Answer 5.)
β 5/3 = 6/x + 2
β x = -18
Answer 6.)
β x - 7/5 = -3
β x = -8/5
Answer 7.)
β 4/5x - 3 = 2/3x + 5
β 12x - 10x = 120
β x = 60
Answer 8.)
β 6x β 3 = 2 + 4x β 11
β 2x = -6
β x = -3
Answer 9.)
β 3 β (4βx) = 5 + 3(xβ4)
β 3 - 4 + x = 5 + 3x - 4
β -1 + x = 1 +3x
β x = -1
Answer 10.)
β 10 + 5x β 2 = 2 β 3x + 6
β 8 + 5x = 8 - 3x
β x = 0
