A= Anthony
D=Daniel
M=Mya
A=2D
M=D+6
Add them all together
A+D+M=102
Substitute
(2D)+(D)+(D+6)=102
4D+6=102
4D=96
D=24
M=D+6
M=24+6
M=$30
Hope this helps.

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 7x + 10
y = -4x - 23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 7x + 10 = -4x - 23
- [Addition Property of Equality] Add 4x on both sides: 11x + 10 = -23
- [Subtraction Property of Equality] Subtract 10 on both sides: 11x = -33
- [Division Property of Equality] Divide 11 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = 7x + 10
- Substitute in <em>x</em>: y = 7(-3) + 10
- Multiply: y = -21 + 10
- Add: y = -11
If you add them all up then the answer is 19!
