Step-by-step explanation:
Answer:
(a) The system of the equations has no solution.
(b) The system of the equations has many solutions
Step-by-step explanation:
(a) To find the solutions of the following system of equations you must:
Multiply by 2:
Subtract the equations
0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system you must:
Isolate x for
Substitute into the second equation
The system has many solutions.
Isolate y for
X + 3 because in math two negatives equal a positive
The total of two whole numbers one after another is 33. for example 10 + 11 (two consecutive integers) = 21
Let’s call the amount of pants x and the amount of shirts y.
12y + 21x = 240
y + x = 14 which could be changed to x= 14-y
now you plug it into the first equation
12y + 21 (14 - y) = 240
12y + 294 - 21y = 240
add the similar terms
12y - 21y = 240 - 294
-9y = -54
cancels the minus signs on both sides
9y = 54
y= 6
now you plug y = 6 into the equation x = 14-y
x = 14 - 6
x = 8
answer: Pam bought 8 pants and 6 shirts
