Question

solve each equation. 2) 3 + r = 2 what is the value of r? r = 1 r = -1 r = 0

Explanation:

Step1: Isolate the variable r.

Subtract 3 from both sides of the equation $3 + r=2$. So, $3 + r-3=2 - 3$.

Step2: Simplify both sides.

On the left - hand side, $3-3 + r=r$, and on the right - hand side, $2-3=-1$. So, $r=-1$.

Answer:

$r = - 1$
