2 answers:
Answer:
Answer 1.)
⇒ 4x - 15 + 2x = x +20
⇒ 6x -15 = x +20
⇒ 5x = 35
⇒ x = 7
Answer 2.)
⇒ 2(2x−5)=20−x
⇒ 4x - 10 = 20 - x
⇒ 5x = 30
⇒ x = 6
Answer 3.)
⇒ 3−4x=10x+10
⇒ 14x = -7
⇒ x = -1/2
Answer 4.)
⇒ 4(2x−1)=−10(x−5)
⇒ 8x - 4 = -10x + 50
⇒ 18x = 54
⇒ x = 3
Answer 5.)
⇒ 5/3 = 6/x + 2
⇒ x = -18
Answer 6.)
⇒ x - 7/5 = -3
⇒ x = -8/5
Answer 7.)
⇒ 4/5x - 3 = 2/3x + 5
⇒ 12x - 10x = 120
⇒ x = 60
Answer 8.)
⇒ 6x − 3 = 2 + 4x − 11
⇒ 2x = -6
⇒ x = -3
Answer 9.)
⇒ 3 − (4−x) = 5 + 3(x−4)
⇒ 3 - 4 + x = 5 + 3x - 4
⇒ -1 + x = 1 +3x
⇒ x = -1
Answer 10.)
⇒ 10 + 5x − 2 = 2 − 3x + 6
⇒ 8 + 5x = 8 - 3x
⇒ x = 0
