If: -5 = 7+3r then the value of r works out as -4
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
It equals 24.
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
1)5r+7=13+2r+3r 2)5r+7=13+5r 3)5r's cancel 7=13 4)Subtract thirteen on both sides 7 =13 -13 -13 5)Answer is no solution because -6 doesn't equal to 0. -6=0 NO SOLUTION!!! Have fun with math!

It is (7 + a)r.
it is 28
