Answer:
y= (-1/8)X-(3/8)
Step-by-step explanation:
8y=-X-3
divide over the 8
y=(-1/8)X-(3/8)
Say the total allowance is X.
4/9X=$28
Therefore 28/(4/9) = $63

Answer:
Step-by-step explanation:
The given equations are:
2a+7b=0 and 3a-5b=31
Statement Reason
1. 10a+35b=0, 21a-35b=217 (Multiply first equation by 5 and second by 7)
2. 31a=217 (Adding both the equations)
3. a=7 (Dividing both sides by 31)
4. 2(7)+7b=0 (Substituting a=7 in first equation)
5.14+7b=0 (solving step 4)
6. 7b=-14 (Subtracting 14 on both sides)
7.5, 6.5 also try searching midpoint formula with what u have it’s pretty basic math
