If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
Yes, because: x+7 = 23 x = 23-7 x = 16
If x=4 then 2x+7 =
If the x=4, then its equivelent to 12 + 4, which equals 16.
x = 7
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
Yes, because: x+7 = 23 x = 23-7 x = 16
16 x 3/4 = 12
If x=4 then 2x+7 =
49/16 = (7^2)/(4^2) = (7/4)^2 = ((4/7)^-1)^2 = (4/7)^-2 Thus as (4/7)^2 = 49/16 and 49/16 = (4/7)^-2 (4/7)^x = (4/7)^-2 Therefore x = -2.
If the x=4, then its equivelent to 12 + 4, which equals 16.
20 - 4 = 16
4 x 4 = 16
x = 7
16 = 1 x 16 = 2 x 8 = 4 x 4
16 times 7 equals 112.
