the answer is -10r

What is ; -r-8+6r=-13.=]

5s-r

r=8

6r+2=2 subtract 2 on each side. 6r=0 divide each side by 6 r=zero

The 'solution' is the number that 'r' must be in order to make the statement true.Here's how to find it:6r - 1 + 6r = 11Add 1 to each side:6r + 6r = 12Clean up the left side:12r = 12Divide each side by 12:r = 1

-6r-5 = 7-12r 12r-6r = 7+5 6r = 12 r = 2

-2r

5 - 710 - 6r = -93-705 - 6r = -93 705 + 6r = 93 6r = 93 - 705 = -612 r = -612/6 = -102

12 - 6r = 2r + 36Add 6r to each side:12 = 8r + 36Subtract 36 from each side:-24 = 8rDivide each side by 8:r = -3

Commutatitivity of addition in the fact that you can change the order of 11s and 3t. But also associativity of addition in that you can write the sum of three terms without the need for brackets to show which addition needs to be performed first.

-6r + 1 = -17, then (17+1)=18=6r, so r=(18/6)=3. The answer is r=3

If that's the equation 6r + 7 = 13 + 7r, r = -6

5r + r = 6r

If: 5/6r = 2/3 then r = 5/4 or 1.25

r2+6r-7 = (r+7)(r-1) when factored

3r + 3r + 2t = 6r + 2t

-6r - s

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

9r = 3r + 6 subtract 3r from both sides 6r = 6 divide both sides by 6 r=1 ■

(6r - 7v)(3r - 2v)
