4 0

Answer:

5

Step-by-step explanation:

If X equals 2, then 3 times X would be 6. This is because if a number and a variable are put together, you have to multiply them. 6-1 is 5.

1. Since 2x2x does not contain the variable to solve for, move it to the right side of the equation by subtracting 2x2x from both sides.−3y=−2x+8-3y=-2x+8Divide each term by −3-3 and simplify.
Divide each term in −3y=−2x+8-3y=-2x+8 by −3-3.<span><span>−3y−3=−2x−3+8−3</span><span>-3y-3=-2x-3+8-3</span></span>Simplify the left side of the equation by canceling the common factors.

Answer:

<h2>M(-a, b)</h2>

Step-by-step explanation:

Use the formula of a midpoint:

\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have the points P(-2a, 0) and Q(0, 2b). Substitute:

x=\dfrac{-2a+0}{2}=\dfrac{-2a}{2}=-a\\\\y=\dfrac{0+2b}{2}=\dfrac{2b}{2}=b
