To solve this equation, we are going to isolate the variable x. To do this, we are going to begin by adding x to both sides because this will cancel out the negative x on the right side of the equation.

x + 2 + x = -x + x - 2
When we combine like terms, we get:
2x + 2 = -2
Next, we will try to continue to isolate the variable by subtracting 2 from each side to get the 2x term on the left by itself.
2x + 2 -2 = -2 -2
When we combine like terms, we get:
2x = -4
Finally, to get x by itself we must divide by 2 to undo the multiplication of the coefficient of the term 2x.
2x/2 = -4/2
When we perform the division, we get:
x = -2
Therefore, x = -2.
We can check this answer by plugging it back into the original equation. Our answer is verified because 0=0.
Your answer is that x = -2.
Hope this helps!

45.50 is 30% of what number

m_a_m_a [10]

Answer:

31.85

Step-by-step explanation:

to subtract 30 percent from 45.50 just divide the percentage (30) by 100 subtract this value form 1 then multiply it by the initial value (45.50) so

final value = 45.50 x ( 1 - $\frac{30}{100}$ )

final value = 45.50 x ( 1 - 0.3)

final value = 45.50 x (0.7)

final value = 31.85

subtract 30% is the same as discount 30% this operation could be for example a 30% discount on 45.50

note: 0.3 can be found just by moving the decimal point 2 places to the left $\frac{30}{100}$ = 0.3 as a decimal

SHORT ANSWER Graph and label point W(4, –1) <br> on the coordinate plane.

Lunna [17]

Answer:

Step-by-step explanation:

a coordinate point is (x, y) so for point W (4, -1), 4 is the x-coordinate and -1 is the y-coordinate.

Start at the origin (O). Go 4 units to the right (along the x-axis in a positive direction) and then 1 unit down (in the y plane in a negative direction).
