T+(3-2t)=4t+1. Assuming the two T's , T and t are the same variable, lets proceed. t+(3-2t)=4t+1 3-t=4t+1 2-t=4t 2=5t last step is yours
Subtract 21 from both sides. If that's + 4t, the answer is (t - 3)(t + 7) and t = 3, -7 If that's - 4t, the answer is (t + 3)(t - 7) and t = -3, 7
4t-10
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
-2t = -10
4t-3 is not equal to 13+4t
4t - 3 = 19 4t = 19 +3 = 22 t = 22/4 t = 5.5
If that's 4t3, that indicates that t has been cubed, which is to say it represents t x t x t.
r + 2t = -3 . . . . (A)3r - 4t = -9 . . . . (B)2*(A) + (B): 2r + 4t + 3r - 4t = -6 - 95r = - 15 so r = -3substituting in (A), t = 0So the answer is (r, t) = (-3, 0)r + 2t = -3 . . . . (A)3r - 4t = -9 . . . . (B)2*(A) + (B): 2r + 4t + 3r - 4t = -6 - 95r = - 15 so r = -3substituting in (A), t = 0So the answer is (r, t) = (-3, 0)r + 2t = -3 . . . . (A)3r - 4t = -9 . . . .

T+(3-2t)=4t+1. Assuming the two T's , T and t are the same variable, lets proceed. t+(3-2t)=4t+1 3-t=4t+1 2-t=4t 2=5t last step is yours
28 t2 - 17 t - 3 = (7t + 1) x (4t - 3)
Subtract 21 from both sides. If that's + 4t, the answer is (t - 3)(t + 7) and t = 3, -7 If that's - 4t, the answer is (t + 3)(t - 7) and t = -3, 7
4t-10
I suppose you mean t2-4t=21minus 21 from both sideswe get-> t2-4t-21=0find 2 numbers that multiply to get 21, and combined each other to get 4.3&7 work, 3*7=21, 3-7=-4--> (t-7)(t+3)=0Ex: X*Y=0, that can be mean X or Y =0, or X andY=0Our equation (t-7)(t+3)=0, means that t-7=0.......t+3=0t-7=0------->t=7t+3=0------->t=-3*Remember* Quadratic equation mostly has two answers.
t in this problem equals -3. 4t- 8+ 25= 5 -25 -25 4t- 8= -20 +8 +8 4t= -12 /4 /4 t= -3
9t = 4t + 120 9t-4t = 4t - 4t + 120 5t = 120 5t/5 = 120/5 t = 24 24 is your answer
4t-523 = -519
