Solve for x. 85 = −6x + 7 + 4x a. 78 b. 39 c. −39 d. −78

           x = -39

Step-by-step explanation:

85= -6x+7+4x      combine like terms (-6x, 4x)

85= -2x+7            subtract 7 from both sides

78= -2x                  divide both sides by -2

x= -39        

-39

Step-by-step explanation:

combine like term.

85= -2x+7

1st subtract 7 from both sides

78=-2x

then divide both sides by -2

-39=x

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
