5+3R = 5R-19bring all the variables to the left side (in this case it will be R)
remember when you bring numbers or variables the sign changes, if the variable or number is positive it shall change to negative and vise versa.
3R-5R= -19-5
-2R = -24
R= -24/-2= 12
checking:
5+3R = 5R-19
so now you substitute R to see if it equation is correct.
5+3(12)= 5(12)-19
5+36=60-19
41=41 SO CORRECT!

How do you Factor 3r squared equals 13r plus 10?
(3r + 2)(r - 5)
What is 12r- 8- 12 equals?
It is 12r - 20 or 4*(3r - 5)
Solve 4r plus 3 equals 3r- 2 for r?
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
What is 5r plus 7 equals 13 plus 2r plus 3r?
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!
5 plus 5 plus 5 equals 550?
No. It equals 15.
What is -5 equals 7 plus 3r?
If: -5 = 7+3r then the value of r works out as -4
How do you Factor 3r squared equals 13r plus 10?
(3r + 2)(r - 5)
What is r in this equation and how do you do it minus 5 equals 7 plus 3r?
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
Can r plus 2r - 3r be simplified?
5
What is -5r plus 8r plus 5?
-5r + 8r + 5 = 3r +5
-7p plus 5r-6p plus 3r?
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
What is 12r- 8- 12 equals?
It is 12r - 20 or 4*(3r - 5)
If a rectangle has a width of 3r and a length of 5 plus 7r what is its perimeter?
20r + 10
Solve 4r plus 3 equals 3r- 2 for r?
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
What is the answer to this problem If 1 plus 5 equals 12 and 2 plus 10 equals 24 and 3 plus 15 equals 36 then 5 plus 25 equals what?
5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
What is the radix of the number if the solution to quadratic equation x2-10x plus 31 equals 0is x equals 5and x equals 8?
Solution:(5r0)2 - (1r1+0r0)*5 + 3r1+1r0 = (8r0)2 - (1r1+0r0)*8 + 3r1+1r0 25 - 5r + 3r + 1 = 64 - 8r + 3r + 13r - 39 = 0r = 13Result: radix r = 13
What is 5 plus 7 plus 7 plus 5 equals?
It equals 24.
