Simplifying the equations:
4a + 8a = 12a12y - 7y = 5y
So, the equations become:
12a = 2045y = 315
Solve for a and y by dividing both sides by their respective numbers:
a = 204 / 12a = 17
y = 315 / 5y = 63
Therefore, the solutions for a and y are:a = 17y = 63
Simplifying the equations:
4a + 8a = 12a
12y - 7y = 5y
So, the equations become:
12a = 204
5y = 315
Solve for a and y by dividing both sides by their respective numbers:
a = 204 / 12
a = 17
y = 315 / 5
y = 63
Therefore, the solutions for a and y are:
a = 17
y = 63
