You are searching for the value of r.-7r + 6 = 9 - 6r + 1Notice the 9 and the 1 on the right side. Since they are common factors (terms not attached to x), they can be added.-7r + 6 = -6r + 10Subtract 6 from both sides to eliminate the 6 on the left.-7r = -6r + 4Add 7r to both sides, leaving r-terms on only one side.0 = r + 4Subtract 4 from both sides, so one side is constant and the other is the variable.-4 = rThe answer is -4 is equal to r.
9r-1?
100 - 7r = 44 Subtract 100 from both sides: -7r = -56 Divide both sides by -7: r = 8
6p - pq 7pr factorizing = -1
"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other.
It is a string of algebraic terms.
7r-43 = -36
the answer is 7r.1 hope it helps
7(r-12) A 7 is taken out because it is a common factor to both terms.
12 + 8r - 6 = 7r - 5 - 3 8r +6 = 7r -8 r = -14
7r = r + r + r + r + r + r + r or r7
I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
2r + 7r - 6t - r + 7t = 8r + t
one that won't talk to one another because they don't like each other... NO, seriously, they are terms that are different. For example x^2+2x+3x-4x^2. The x^2 terms are like terms and the x^2 terms and the x terms and unlike because they are different. Just like x and y, or apples and oranges.
i think yes, because you can combine 2 and -2, which are like terms, so why not 2a and -2a?
-16x + 2 + 18x 'Like' terms are those which contain the same factor; in this case 'x' So taking -16x + 18x =. 18x - 16x = 2x So it becomes 2x + 2 NB The '2' , on its own is a constant, so is not a 'like' term. Similarly, something like 2x^3 + 3x^2 + x^3 - x^2 . The 'x^3' are like terms , and the 'x^2' are like terms, but 'x^3' is unlike to 'x^2'. So collecting like terms it would become 4x^3 + 2x^2 . When you do something like 2x^2(2x + 1) , this is NOT collecting like terms , but FACTORING. Hope that helps!!!!!
All depend on how big is the letter,i like to use a 5rl on small letters or 7r for bigger letter
