Question

o) 2(3-x) = 3(x-4)+15
p) 3(5-x)-3(1-2x) = 42
q) (4x+6)-2x = (x–6)+10+14
r) (x-3)-(x+2)+2(x-1)-5 = 0
s) 3x-2(4x-3) = 2–3(x-1)


PRECISO DAS CONTAS ​

Answer 1

o) 2(3-X)=3(X-4)+15

6 - 2X = 3X - 12 + 15

- 2X - 3X = - 12 + 15 - 6

- 5X = - 3 (-1)

5X = 3

X = 3/5

p)2(5-X)-3(1-2X)=42

10 - 2X - 3 + 6X = 42

- 2X + 6X = 42 - 10 + 3

4X = 35

X = 35/4
