Answer:
She bought 2 long sleeve shirts and 4 t-shirts
Step-by-step explanation:
Let number of long sleeves = x
Let number of t-shirts = y
x+y=6
∴y=6-x
14x+4y=44
14x+4(6-x)=44
14x+24-4x=44
10x=20
x=2
y=6-x
=6-2=4
ANS: She bought 2 long sleeve shirts and 4 t-shirts

- Equality Properties
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
a + 4b = -4
a + 10b = -16
<u>Step 2: Rewrite Systems</u>
a + 4b = -4
- Subtract 4b on both sides: a = -4 - 4b
<u>Step 3: Redefine Systems</u>
a = -4 - 4b
a + 10b = -16
<u>Step 4: Solve for </u><em><u>b</u></em>
<em>Substitution</em>
- Substitute in <em>a</em>: -4 - 4b + 10b = -16
- Combine like terms: -4 + 6b = -16
- Isolate <em>b</em> term: 6b = -12
- Isolate <em>b</em>: b = -2
<u>Step 5: Solve for </u><em><u>a</u></em>
- Define equation: a + 4b = -4
- Substitute in <em>b</em>: a + 4(-2) = -4
- Multiply: a - 8 = -4
- Isolate <em>a</em>: a = 4
