Let x be the number of people at University B

x + (x+3.5) = 9.5
2x +3.5 = 9.5
2x = 6
x = 3 million students at University B

x + 3.5 = 3 + 3.5 = 6.5 million students at University A

<u>Algebra I</u>

Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

5x - 2y = 9

3x + 4y = -5

<u>Step 2: Rewrite systems</u>

10x - 4y = 18

3x + 4y = -5

<u>Step 3: Solve for </u><em><u>x</u></em>

Add to equations together: 13x = 13
Divide 13 on both sides: x = 1

<u>Step 4: Solve for </u><em><u>y</u></em>

Define: 3x + 4y = -5
Substitute in <em>x</em>: 3(1) + 4y = -5
Multiply: 3 + 4y = -5
Isolate <em>y </em>term: 4y = -8
Isolate <em>y</em>: y = -2

And we have our final answer!
