it equals 72. just do 12 X 6
-6
-10 x -6 = 60 60 + -12 = 48
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
5=4x 1.25=x
6 + 2x = x - 6 2x - x = -6 -6 x = -12
x=2
X=2
negative 1
x 5x-3x +6=-12, x 2x +6=-12,3x+6=-12, move the x and it's very easy 12/6=2 ...But the answer is negative so the x is equal to -2 and the answer is -12...I .
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
x+x+2+x+4+x+6=42(x+x+x+x)+(2+4+6)=424x+12=424x=30x=15/2or 7 and 1/2
