What is the solution to this equation?
9 - 4x + 7 x = 15

8

Step-by-step explanation:

1. subtract 9 from both side (-4x+7x=24)

2. add both of the x's (-4x+7x=3x)

3. your equation is now 3x=24

4. divide by 3 on both sides

5. 24/3=8

r and t.

both are 64 degrees.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
