You first move the constant to the right side and change its sign (7x = 58 -9). You then subtract the numbers (58-9=49), so you are left with 7x = 49. Then you divide both sides by 7 to isolate the variable (x). The answer is x = 7.

timofeeve [1]

Answer:

Step-by-step explanation:

The formula of a midpoint:

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

We have (2, 3) and (12, 3).

Substitute:

$x=\dfrac{2+12}{2}=\dfrac{14}{2}=7\\\\y=\dfrac{3+3}{2}=\dfrac{6}{2}=3$

Whats 15-b=4b-5(5-3)

Gala2k [10]

15-b=4b-5(5-3)

Multiply the bracket by -5

(-5)(5)=-25

(-5)(-3)=15

15-b=4b-25+15

15-b=4b-10

Move 15 to the other side

Sign changes from +15 to -15

15-15-b=4b-10-15

-b=4b-25

Move 4b to the other side.

-b-4b=4b-4b-25

-b-4b=-25

-5b=-25

divide both sides by -5

-5b/-5=-25/-5

Answer: b=5
