Step-by-step explanation:
it was pretty simple
Maria has 19 hats.
b=beth
m=maria
Equations: 2b+5=m
b+m=26
plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats
