Answer:
x = -(3/2)
Step-by-step explanation:
i'm going to assume that the left side is (2/3)x and not 2/(3x). If so let me know and i'll change it.
(2\3)x =-1 (multiply both sides by 3)
2x = -1 (3)
2x = -3 (divide both sides by 2)
x = (-3) / 2
x = -(3/2)
3.9 · 0.5 + 4 5/6 ÷ 3 3/7
1.95 + 4 5/6 ÷ 3 3/7 multiplication left ot right
1.95 + 29/6 ÷ 24/7 convert to improper fraction
1.95 + 29/6 · 7/24 divide by fraction same as multiplication by reciprocal
1.95 + 203/144 multiply
1.95 + 1.40 (and a teensy bit more)
3.35
