It’s 2 equations so in order to solve the previous system, you can use different methods, as for example substitution or addition of equations. In this case, you use the second one, due to the fact you have 7x in one equation and -7x in the other equation. In this way you can easily eliminate variable x and then solve for y. With the value of y you can replace in any of the two equations and solve for x.
7x-y=-1
-7x+3y=-25
Summarizing, you proceed as follow:
- add up the given equations
7x - y = -1
-7x+3y=-25
——————
0 +2y=-26
- solve for y in the previous equation
2y=-26
y=-26/2
y=-13
- replace the obtained value of y in one of the given equations, and solve for x
7x-(-13)=-1
7x+13=-1
7x=-1-13
7x=-14
x=-14
x=-14/7
x=-2
Hence, the solution of the given systems of equation is:
X=-2
Y=-13
Answer:
Answer:option B 100%
Step-by-step explanation:
Since direct materials are added into production process at the end,so it will be more likely to be 100% completed.
Answer:
y = -7x + 17
Step-by-step explanation:
you want to isolate the 'y' variable, start by distributing -7 on the right side
y + 4 = -7x + 21
now subtract 4 from each side
y = -7x + 17
You would travel 73.333334ft per second because 50 miles/hour would make 73.333333repete foot/second.
