3/4x - 7 = -1

pls explain!!

Step-by-step explanation:      

Step 1: Add 7 to both sides.

Step 2: Simplify

Step 3:  Multiply both sides by 4

Step 4: Simplify

Step 5: Divide both sides by 3

Step 6: Simplify

Explanation in words (Short Form)

-  The first step is to add 7 to both sides and the answer will result as 3/4x=6.

- The second step is to multiply both sides by 4/3 and the final answer will result as x = 8.

Hope this helps.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
