Hope you can see and understand what I wrote
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
Simplifying
2(n + 20) = 110
Reorder the terms:
2(20 + n) = 110
(20 * 2 + n * 2) = 110
(40 + 2n) = 110
Solving
40 + 2n = 110
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-40' to each side of the equation.
40 + -40 + 2n = 110 + -40
Combine like terms: 40 + -40 = 0
0 + 2n = 110 + -40
2n = 110 + -40
Combine like terms: 110 + -40 = 70
2n = 70
Divide each side by '2'.
n = 35
Simplifying
n = 35
