7(2e-1)-3=6+6e
14e-7-3=6+6e
14e-10=6+6e
+10 +10
14e=16+6e
-6e -6e
8e=16
8e/8=16/8
E=2
Answer:
16
Step-by-step explanation:
if x=23, 23-7=16
3 doubled equals 6, so every second multiple of three is also a multiple of six.
Examples:
3 times 4 is 12, and 6 times 2 is 12
3 times 6 is 18, and 6 times 3 is 18
3 times 8 is 24, and 6 times 4 is 24
