If you would like to solve for x, you can do this using the following steps:
7x + 15 = 38
7x = 38 - 15
7x = 23
x = 23/7
The correct result would be 23/7.
1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
Need a number to solve ........
I hope this helps you
1/2-3/7

1/14
We calculate it by multiplying the place value and face value of the digit. For instance: If we consider a number 45. Here the digit 4 is in the tens column.
