89+2t = 10t+25 89-25 = 10t-2t 64 = 8t t = 8
6t - 4x
The expression 15-t plus 8t-13 simplifies to 7t + 2.
It is an expression that can be simplified to -8t-38
2t2+8t+5 = 0 The expression in this quadratic equation is not so simple to factorise because 5 is a prime number which has only two factors (itself and one) but we can get a near enough solution by using the quadratic equation formula. Using the quadratic equation formula gives the solution as: t = - 0.7752551286 or t = - 3.224744871
It is an expression in two variables, z and t. It can be simplified to 14z + 2t or 2*(7z + t)
8t^2 - 11t - 4
7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
It is a linear expression in two variables. As an expression it cannot be solved. Furthermore, to solve equations in two variables you need at least two linear equations.
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
-3t3 + 23t2 + 8t = -t(3t2 - 23t - 8) = -t(3t + 1)(t - 8)
t=-2
