I WILL GIVE BRAINLIEST IF YOU SOLVE THEM ALL CORRECTLY!!! THANKS!
Find the numerical values of the following expressions:
a) | 3 | a | +5 | b | if a=−2; b=−1
b) |2x−3y| if x=0.5; y=−0.7
c)| 4 | a | +8−a | if a=−2
d) |−3 | x | +2x−1 | if x=−5

What is the solution to the system of the equations? x = y - 3 x + 3y = 13
