Question

Solve x=7-2t for t.

Answer 1

Answer:

The value of the provided equation for t is $t=\frac{-x+7}{2}$.

Step-by-step explanation:

Consider the provided equation.

$x=7-2t$

We need to solve the equation for t.

Subtract 7 from both the sides.

$x-7=7-7-2t$

$x-7=-2t$

Divide both the sides by -2.

$\frac{x-7}{-2}=\frac{-2t}{-2}$

$\frac{-(x-7)}{2}=t$

$t=\frac{-x+7}{2}$

Hence, the value of the provided equation for t is $t=\frac{-x+7}{2}$.

Answer 2

x=7-2t

Move 7 to the other side. Sign changes from +7 to -7.

x-7=7-7-2t

x-7=-2t

Divide by -2 for both sides

x/-2-7/-2=-2t/-2

x/2+7/2=t

Answer: t= x/2+7/2 or t=7/2+x/2
