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
2x7 = 14 x7 = 7 3x7 = 3*7 = 21
x equals 14
Depends on where the parentheses are. X(7-4) + X7 + 4 = 10X + 4 X(7-4) + X(7+4) = 14X
x = 14
x=28
x = 0
That's a total of 378
x7
x = 11 - 2y and 14 - 2y. This means that 11 = 14. Is there a typo in the question?
