2(r+5)-4(r-1)=32
We simplify the equation to the form, which is simple to understand
2(r+5)-4(r-1)=32
Reorder the terms in parentheses
+(+2r+10)-4*(r-1)=32
Remove unnecessary parentheses
+2r+10-4+*(+r-1+)=+32
Reorder the terms in parentheses
+2r+10+(-4r+4)=32
Remove unnecessary parentheses
+2r+10-4r+4=+32
We move all terms containing r to the left and all other terms to the right.
+2r-4r=+32-10-4
We simplify left and right side of the equation. -
2r=+18
We divide both sides of the equation by -2 to get r.
r=-9
r=-9 is th answer
