10 x 7 or 70 square feet

47/10 x 43/7 = 4X10+7/10 X 4X7+3/7 = 47/10 X 31/7 = 47X31/10X7 = 1457/70 = 2057/70

x=7 look at the bottom for the reason: First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21) so, 5x + 2x + 3x + 10x = 140 20x = 140 40/20 = 7 so, (5x7) + (2x7) + (3x7) + (10x7) = 140 so, 35 + 14 + 21 + 70 = 140

X plus 7-12?

7=x+1 6=x

X plus 7-12?

7=x+1 6=x

x-7+7=11+7 x=11+7 x=18

2x + 7 = x + 3 x + 7 = 3 x = -4

7 + 1x + 5 = 12 + x

x sq + 8x + 7 = (x + 7) (x + 1)

If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
