Answer:
z = -3
Step-by-step explanation:
Simplifying
3z + -3 = 2z + -6
Reorder the terms:
-3 + 3z = 2z + -6
Reorder the terms:
-3 + 3z = -6 + 2z
Solving
-3 + 3z = -6 + 2z
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-2z' to each side of the equation.
-3 + 3z + -2z = -6 + 2z + -2z
Combine like terms: 3z + -2z = 1z
-3 + 1z = -6 + 2z + -2z
Combine like terms: 2z + -2z = 0
-3 + 1z = -6 + 0
-3 + 1z = -6
Add '3' to each side of the equation.
-3 + 3 + 1z = -6 + 3
Combine like terms: -3 + 3 = 0
0 + 1z = -6 + 3
1z = -6 + 3
Combine like terms: -6 + 3 = -3
1z = -3
Divide each side by '1'.
z = -3
Simplifying
z = -3
Answer:
ordered pair(-2 , 3) is the solution
Step-by-step explanation:
y=x+5
y=-2x-1
x+5 = -2x-1 substitution
x+5+2x-5 = -2x-1+2x-5
3x = -6
x = -2
y = -2+5 = 3
ordered pair(-2 , 3) is the solution
Answer:
5.25 hours
Step-by-step explanation:
The calculation of the time needed to schedule for all seven applications is shown below:
Since 3 by 4 is required of an hour to meet you show them
i.e.
= 3 ÷ 4 of an hour
= 3 ÷ 4 × 60 minutes
= 45 minutes
Now for seven applications, the time would be
= 7 × 45 minutes
= 315 minutes
And, one hour = 60 min.
So, the time required is
= 315 minutes ÷60 minutes
= 5.25 hours
