Answer: 5x-7
Step-by-step explanation:
Answer:
A = 24
Area for a triangle = 1/2 b * h
-4.2c+4.8d is the answer to this equation.
It might be no solution:
steps-
x=5-y
x+y=15
substitute the x(which is the top problem) into the second one.
(5-y)+y=15
cancel it out
(5-y)+y=15
-5. -5
a negative plus a positive is gonna equal 0
-y+y=15-5
0=10
that is no solution..
