21x21 equals 7x7x9
x = 9
sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5sqrt(x7) = sqrt(x6*x) = x3*sqrt(x)or, more simply,sqrt(x7) = x7/2 = x3.5
91 x 1 or 13 x7
X +13 equals 22, X equals nine
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
Depends on where the parentheses are. X(7-4) + X7 + 4 = 10X + 4 X(7-4) + X(7+4) = 14X
x = 13
That's a total of 378
If 5x + x² > 100, then x is notAnother Answer:-If 2x-17 = 13 then x = 15
x7
x/13 = 15 x = 15(13) x = 195
