We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i
X-1/2=15 1/4
15 1/4 = 15*4 + 1 = 61/4
61/4
x - 1/2 = 61/4
+1/2 +1/2
61/4 + 2/4 = 63/4
x = 63/4
Answer:
4/9
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 16 and 36 is 4
Divide both the numerator and denominator by the GCD
16 ÷ 4
36 ÷ 4
Reduced fraction:
4
9
Therefore, 16/36 simplified to lowest terms is 4/9.
4 and 15. You can guess and check or use algebra.
