Given the equation 5x - 7 = 18. What is the first step in solving this equation?
Adding 7 to both sides.
Subtracting 5 from both sides.
Subtracting 7 from both sides.
Dividing by 5 on both sides.

The answer is adding 7 to both sides.

Step-by-step explanation:

5x-7=18

  +7  +7

5x= 25

x=5

Adding 7 to both sides.

Step-by-step explanation:

You always do the "inverse" of the number without the variable next to it and either "add" or "subtract" it to the other side.

Ex: 7x - 3 = 18

In this case, you would add the 3 to the other side.

7x - 3 = 18

    + 3    +3

7x = 21

7x    7x

x = 3

the answer is two. hope this !

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
