Question

System of equations

1). 2/5x + 5/6y=6
Y/3=x/2+9.

2).4x+2=3y+5
2y-1=x+2

These are my last two problems and I can t get it

Thanks for the help

Answer 1

get rid of fractions to make things easier:

12x + 25y = 180
3x - 2y = -9
or

12x+25y = 180
12x-8y = -36
33y = 216
11y = 72
y = 72/11
x = 15/11

rearrange to standard format:

4x-3y = 3
x-2y = -3
or
4x-3y = 3
4x-8y = -12
5y = 15
y = 3
x = 3
