Can You Solve R+1-3t>t-20 And Show All Steps?

You didn't indicate which variable we're solving for, so I'll show you solutions for both R and t;

First we'll solve for R
R + 1 - 3t > t - 20
add 3t to both sides;
R + 1 > 4t - 20
subtract 1 from both sides;
R > 4t - 21

Or we can solve for t
R + 1 - 3t > t - 20
add 3t to both sides;
R + 1 > 4t - 20
add 20 to both sides;
R + 21 > 4t
flip the equation around and divide by 4;
t < R + 21
