Answer:
Answer 1.)
โ 4x - 15 + 2x = x +20
โ 6x -15 = x +20
โ 5x = 35
โ x = 7
Answer 2.)
โ 2(2xโ5)=20โx
โ 4x - 10 = 20 - x
โ 5x = 30
โ x = 6
Answer 3.)
โ 3โ4x=10x+10
โ 14x = -7
โ x = -1/2
Answer 4.)
โ 4(2xโ1)=โ10(xโ5)
โ 8x - 4 = -10x + 50
โ 18x = 54
โ x = 3
Answer 5.)
โ 5/3 = 6/x + 2
โ x = -18
Answer 6.)
โ x - 7/5 = -3
โ x = -8/5
Answer 7.)
โ 4/5x - 3 = 2/3x + 5
โ 12x - 10x = 120
โ x = 60
Answer 8.)
โ 6x โ 3 = 2 + 4x โ 11
โ 2x = -6
โ x = -3
Answer 9.)
โ 3 โ (4โx) = 5 + 3(xโ4)
โ 3 - 4 + x = 5 + 3x - 4
โ -1 + x = 1 +3x
โ x = -1
Answer 10.)
โ 10 + 5x โ 2 = 2 โ 3x + 6
โ 8 + 5x = 8 - 3x
โ x = 0
