11x+9=7x+21
11x-7x=4
4x+9=21
21-9=12
4x=12
12 divided by 4= 3
x=3
8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7
11x - 21 = 7x + 3 4x = 24x = 6
x=3 actually its 7
21
The value of x is -21.
7 and (-3/2)
1) x=21 2) x=14.45
The value of x is 29
2(10)+1
The mathematical statement 31 plus 21 equals 52 as a total.
21+21+19+19=80
The statement 10 plus 21 equals 31 in total. It can also be written as 10 + 21 = 31.
