solve using the addition and multiplication principle 22y5y<65.
I am totally stressed and burned out. I'm sorry. I just can't seem to function anymore. Please help. Thank you so much.

22y5y<65
combine like terms
2  7 y < 65
add 2 to both sides
7 y < 63
divide both sides by 7
y < 9
multiply both sides by 1
change direction of arrow when multiplying by negative number
y > 9
check with y = 8
2  2(8) 5(8)
2 + 16 + 40 = 58 yes less than 65
