8t + 5 = 6t + 1,subtract 6t an 5 from each side,2t = -4t = -2Checking, 8t + 5 = -16 + 5 = -11 and 6t +1 = -12 + 1 = -11
t + 5t + 5 = 6t + 5
t=-2
6t+t = 7t
6t -2t + 5u = 4t - 5u
8t + 5 = 6t + 1,subtract 6t an 5 from each side,2t = -4t = -2Checking, 8t + 5 = -16 + 5 = -11 and 6t +1 = -12 + 1 = -11
t + 5t + 5 = 6t + 5
t=-2
6t+t = 7t
9t2
3t2 + 5t + 6t + 2t2 - 6t - 4is the same thing as 5t2 + 5t - 4.But that's not an 'answer'. There's no question in the original expression.
6t -2t + 5u = 4t - 5u
6t2 - 53t + 40 = 6t2 - 48t - 5t + 40 = 6t(t - 8) - 5(t - 8) = (t - 8)(6t - 5)
2r + 7r - 6t - r + 7t = 8r + t
8t^2 - 11t - 4
6t + 7 when t = -3 is 6*(-3) + 7 = -18 + 7 = -11
