Answer:

x=-1

Step-by-step explanation:

hello :

3x+9-7x=2(x+6)

3x+9-7x=2x+12

3x-2x-7x=12-9

-6x = 6

x=6/-6 = -1

Answer:

x = - \frac{1}{2}

Step-by-step explanation:

Given

3x + 9 - 7x = 2(x + 6), that is

- 4x + 9 = 2x + 12 ( subtract 2x from both sides )

- 6x + 9 = 12 ( subtract 9 from both sides )

- 6x = 3 ( divide both sides by - 6 )

x = \frac{3}{-6} = - \frac{1}{2}

Find x from given equations sin30 + 2 cot^2 30 + x cos^2 30= 8+ tan^2 45 + cos 60​
julia-pushkina [17]

Answer

1/2+2×(sqrt3)^2+x.(sqrt3/2)^2=8+1^2+1/2

1/2+2×3+x.3/4=8+1+1/2

1/2-1/2+6+x.3/4=9

x.3/4=9-6

x.3×4=3

x.3=3×4

x.3=12

x=12/3

x=4.

so, the value of x is 4.

hope it helps you.
