Well, darling, a 2-step equation that equals 21 could be something like 2x + 5 = 21. First, you'd subtract 5 from both sides to get 2x = 16, then divide by 2 to find x = 8. Voila, you've got yourself a sassy solution!

n + 13 = 21. n = 21 - 13
It is an equation and the value of x is 7

It is a linear equation in two dimensional space. Such an equation defines a line in 2-d
It is an equation. Taking it step by step: 17 = 3t - 4 17 + 4 = 3t 21 = 3t 7 = t So the value of t is 7.
