4
Step-by-step explanation:
We convert this word equation to a number equation, then work it out.
7+4x=23 Use 'x' for the number we want to find.
4x=16 Subtract 7 on both sides.
x=4 Divide both sides by 4
To convert a decimal (112) to base 8, divide by eight, keep the quotient and remainder. Repeat with the quotient.
112/8=14 R0
14/8=1 R6
1/8=0 R1
Read the remainders from bottom to top to get 160 (base 8) = 112 (decimal)
1+(1*4)=5
2+(2*5)=12
3+(3*6)=21
5+(5*8)=45
