If 36 = 4r, r = 9
36
Type your answer here... 6R-12 = 2R + 36 subtract 2R from both sides 4R -12 = 36 add 12 to both sides 4R = 48 divide both sides by 4 R = 12
-2=4r+s s=-4r-2 or s=-(4r+2)
4r-48 = -44
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
It is 4r + 12s
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
s = -2 -4r
It is in its simplest form: 4r+r = 5r
4r + 8rs + 28r 4r is a factor of every every term so the expression can be written 4r(1 + 2s +7) NOTE : The original expression can be simplified to 8rs + 32r and thus the factored expression becomes 4r(2s + 8).
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2
