Answer:
x=6
Step-by-step explanation:
2 (x-4) +3 =7
Subtract 3 from each side
2 (x-4) +3-3 =7-3
2(x-4) =4
Divide each side by 2
2(x-4)/2 = 4/2
x-4 = 2
Add 4 to each side
x-4+4 =2+4
x=6
Answer:
x = 324
Step-by-step explanation:
= 27, where x is the unknown number
multiply both sides by 12:
x = 324
36; 351; 66; 1,017; 113,331; 1,968; 537; 417; 3,813
We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have

Similarly, we have

Now we can sum the fractions:

The pattern is going by six, so every time it goes up by six. Therefore, the next number is 158
