Answer:the price for one shirt is $7.5
the price for one pair of pants is $18.5
Step-by-step explanation:
Let x represent the price for one shirt.
Let y represent the price for one pair of pants.
Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that
4x + 3y = 85.5 - - - - - - - - - -1
She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that
3x + 5y = 115 - - - - - - - - - - - 2
Multiplying equation 1 by b3 and equation 2 by 4, it becomes
12x + 9y = 256.5
12x + 20y = 460
Subtracting, it becomes
- 11y = - 203.5
y = - 203.5/ -11 = 18.5
Substituting y = 18.5 into equation 1, it becomes
4x + 3×18.5 = 85.5
4x + 55.5 = 85.5
4x = 85.5 - 55.5 = 30
x = 30/4 = 7.5

Answer:
X<-50
Step-by-step explanation:
multiply both sides by 2, then you move the constant to the right 10-X>60, then subtract the numbers -X>60-10 and for last you just change the sings so that gives u your answer x<-50
