Question

Make x the subject of the formula 7 + x = t

Answer 1

Answer:

x=t-7

Step-by-step explanation:

To make x the subject of the formula 7 + x = t

What we mean is that we want x to stand alone.

So if we want x to stand alone then we will subtract both sides by 7 to make the x stand alone.

-7+7+x=t-7

x = t - 7

So now the final answer becomes;

x = t - 7

Answer 2

Answer:

x = t-7

Step-by-step explanation:

$7 + x = t$

Move 7 to the right side.

Note : That when a number crosses an equality sign , the sign changes.

$x = t - 7$
