You multiply by the conjugate to both the denominator and numerator.
After that you can simplify by canceling the 4 and then you are able to simplify the (h) as well.
1.6+x-3.2=-2+5.6
simplify
-1.6+x=3.6
+1.6 both sides
x=5.2
Answer:
Step-by-step explanation:
y = -x + 9
y - 1 = -(x - 5)
y - 1 = -x + 5
y = -x + 6
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
(a^2 - 5ab) - (7 - 3ab) + (2ab - a^2) = -7
a^2 - 5ab -7 +3ab + 2ab -a^2 = -7 [combine like terms]
a^2 - a^2 = 0
-5ab + 3ab + 2ab = 0
-7 = -7
