218.7 / 6.75 = 32.4 you divide the area by the base
Answer:
x = -2
Step-by-step explanation:
-20 = -4x - 6x + 2(10x)
Simplify both sides:
-20 = -4x - 6x + 20x
Combine like terms:
-20 = 10x
Isolate the variable:
x = -2
Answer: x=95 and y=17
Step-by-step explanation:
X-y=78
6y=7+x
6y-7=x
6y-7-y=78
5y-7=78
5y=85
y=17
x-17=78
x=78+17
x=95
