6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
3a plus 3b-2a plus 5b?
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
4a - 2b plus 6a - 8b?
10a - 10 b
8b plus 11-3b equals 2b plus 2?
Amazing! Exactly the same question was posted here on WikiAnswerslast September 23. What an incredible coincidence!8b + 11 - 3b = 2b + 2That 8b on the left side can be combined with the -3b to make 5b .5b + 11 = 2b + 2Subtract 2b from each side:3b + 11 = 2Subtract 11 from each side:3b = -9Divide each side by 3:b = -3(That's the same answer they got last September.)
If 3a plus 2b equals 24 and 4a plus 8b equals 70 how do you solve for a and b using the elimination method?
Two equations, two unknownsFirst, multiply 3a + 2b = 70 by 4. This gives the equation 12a + 8b = 96. Next, subtract 4a + 8b = 70 from this equation. This result gives 8a = 26, which, solving for a, gives a = 3.25.Substitue the value of a into one of the original equations, which will give b = 7.125.Finally check your results by substituting the values of a and b into each equation.Answer:Given two equations 3a + 2b = 24 ------ (1) and 4a + 8b = 70 ------ (2) We have to solve this by using elimination method.Multiply the equation 3a + 2b = 24 by 4 on both the sides.We get 12a + 8b = 96 ---------- (3)Now, subtract the equation (2) from equation (3)12a + 8b = 96 ---------- (3)4a + 8b = 70 ---------- (2)--------------------------------(12a - 4a) + (8b - 8b) = (96 - 70)8a + 0 = 268a = 26a = 26/8a = 13/4 (Or) a = 3.25Substitute the value of a in the equation (2)4a + 8b = 70 ---------- (2)4(13/4) + 8b = 70.13 + 8b = 708b = 70 - 138b = 57b = 57/8 (Or) b = 7.125
2a plus 3b - 4a plus 5b?
8b -2a
What does 4a-3b-2a-8b?
2a+(-11b)
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
What is 3b-8b?
3b-8b = -5
3a plus 3b-2a plus 5b?
3a + (3b - 2a) + 5b =3a + 3b - 2a + 5b =(3a - 2a) + (3b + 5b) =a + 8b
What is the simplified version of 6b plus 3b plus 8b?
It is 17b when simplified
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
