1.4t−0.4(t−3.1)=5.8<br><br> SOLVE FOR Y

VladimirAG [237]

There is no y in this question, however we can solve for t.

1.4t - 0.4(t - 3.1) = 5.8
1.4t - 0.4t + 1.24 = 5.8
t + 1.24 = 5.8
t = 4.56

Solve for x in terms of r, s and t : s=2x+t/r

Anna007 [38]

For this case we have the following equation:

$s = \frac {2x + t} {r}$

We must clear the value of the variable "x" as a function of r, s and t:

If we multiply by "r" on both sides of the equation we have:

$rs =2x + t$

If we subtract "t" on both sides of the equation we have:

$rs-t = 2x$

If we divide by "2" on both sides of the equation we have:

$x = \frac {rs-t} {2}$

Thus, the value of the variable "x" is:

$x = \frac {rs-t} {2}$

Answer:

$x = \frac {rs-t} {2}$
