It is: 12x

10x+2=12 10x=10 x=1
10x + 10x = 20x
( x^2 + 10x )^2 = ( x^2 + 10 x) ( x^2 + 10x ) = x^4 + 10x^3 + 10x^3 + 100x^2 = x^4 + 20x^3 + 100x^2 <----------------
x = 6 Why? 10x + 8 = 68 Subtract 8 from both sides: 10x = 60 Divide both sides by 10: x = 6
That depends on the numerical values of 'x' and 'y'. When either of them changes, the value of (10x + 4y) changes.
10x + 2 - 62 Subtract '2' from both sides 10x = 60 Divide both sides by '10'/ x = 6 The answer!!!!!
-38-10x = 9x+19 -38-19 = 9x+10x -57 = 19x |: 19 -3 = x Therefore x equals -3
10x-7+x+7 = 11x
(x2+10x+21)/(x+3) = (x+7)
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
