Answer:

-6

Step-by-step explanation:

firstly arrange whole equation,

-2x+7=19

Now, Transpose 7 to RHS (right hand side)

-2x=19-7

-2x=12

Further, seperate coefficient -2 from x

and transpose it to RHS and divide them

x=12/-2

Hence, x= -6

Answer:

a. $x^{2} + 3y^{3}$

b. $3y^{3} -6$

c. $5x -3$

d. -6t - 5

Step-by-step explanation:

When a number has the same variable as another, you can add or subtract them

So for the first one, you can do

$5x^{2} -4x^{2} = 1x^{2} = x^{2}$

(But don't forget the $3y^{3}$ !)

So it is:

$x^{2} + 3y^{3}$

Continue this process for the rest of them
