Solution:

-2.9 - x = -7.4

-x = -7.4 + 2.9

-x = -4.5

x = 4.5

-2.9 - x = -7.4

-x = -7.4 + 2.9

-x = -4.5

x = 4.5

Sol'n:

-2.9-x=-7.4

transpose the variable '-x' to the right side and '-7.4' to the left side of the equation

-2.9+7.4=x

x=4.5

-2.9-x=-7.4

transpose the variable '-x' to the right side and '-7.4' to the left side of the equation

-2.9+7.4=x

x=4.5

Which expression is equivalent to 9x – 3y – 5x + 7y + x + y?
Question 3 options:
**Weegy:** 9x – 3y – 5x + 7y + x + y = 9x - 5x + x - 3y + 7y + y = 5x + 5y
The expression 5x + 5y is equivalent to 9x – 3y – 5x + 7y + x + y. (More)

Addition of similar terms in algebraic expression.

f(x)=9x-5x+x-3y+7y+y

f(x)=(9x-5x+x)-(3y-7y-y)

f(x)=5x-(-5y)

f(x)=5x+5y

f(x)=9x-5x+x-3y+7y+y

f(x)=(9x-5x+x)-(3y-7y-y)

f(x)=5x-(-5y)

f(x)=5x+5y

Solution:

x(x + 3) + x(2x – 4) + 6 = x^2 + 3x + 2x^2 - 4x + 6 = 3x^2 - x + 6

x(x + 3) + x(2x – 4) + 6 = x^2 + 3x + 2x^2 - 4x + 6 = 3x^2 - x + 6

7 x (-3) x (-2)2=?

To get the product;

7x(-3)x (-2)2 =

(-21) x (-4)=

Therefore, the answer is positive 84 because negative(-) times negative(-) is equals to positive.

First, get the value of x

x-13=25

x-13+13=25+13

x=38

Then, substitute the value of x in the equation x-13=25

38-13=25

Therefore x=38

x-13=25

x-13+13=25+13

x=38

Then, substitute the value of x in the equation x-13=25

38-13=25

Therefore x=38
