Question

If RT=36, find the value of x

Answer 1

Answer:

4

Step-by-step explanation:

So we know that RT is 36.

Note that RT is the combined length of RS and ST. Therefore:

$RT=RS+ST$

Substitute. RT is 36, RS is 6x+1 and ST is x+7:

$36=(6x+1)+(x+7)$

Combine like terms and add:

$36=7x+8$

Subtract 8 from both sides:

$28=7x$

Divide by 7:

$x=4$

So, our answer is 4 :)
