When x = 5, the value of the expression –2(x – 10) is

The given expression is

And we have to find the value of the expression when x =5

And for that, we plug 5 for x in the given expression. That is

And difference of 5 and 10 is -5. So we will get

So when x =5, the value of the expression is 10 .

a negative exponent is translated as follows:

so, we have

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
