Answer:
x = - 1
Step-by-step explanation:
Given
- 4(3x - 7) = 40 ( divide both sides by - 4 )
3x - 7 = - 10 ( add 7 to both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
The answer is -1 , because when you add a negative number to a positive number the negative number will subtract , and vise versa.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

isolate the variable y

Divide by -4 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so

The solution of the inequality is the shaded area above the dashed line 
The slope of the dashed line is positive m=1/4
The y-intercept of the dashed line is (0,0)
The x-intercept of the dashed line is (0,0)
