Answer:

Both equations are correct

Step-by-step explanation:

Let

s-----> the cost of the shirt

t-----> the cost of the tie

we know that

[tex]s=34[/tex]

[tex]t=s-18[/tex]

substitute

[tex]t=34-18[/tex] -----> linear equation that represent the situation

rewrite 1

Adds 18 both sides

[tex]t=34-18[/tex] -------> [tex]t+18=34[/tex] ------> Olivia equation is correct

rewrite 2

Subtract t both sides

[tex]t+18=34[/tex] --------> [tex]18=34-t[/tex] ------> Max equation is correct
