8b + 11 - 3b = 2b + 2
5b + 11 = 2b + 2
5b - 2b = 2 - 11
3b = -9
b = -3
5b2 = 8b therefore 5b =8 therefore b = 1.6
8b - 4b = 4b
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
The expression 4a + 8b - 12c represents a mathematical operation involving three terms: 4a, 8b, and -12c. Each term consists of a coefficient (4, 8, -12) multiplied by a variable (a, b, c). To simplify the expression, you can combine like terms by adding or subtracting coefficients of the same variables. The final result will depend on the specific values assigned to the variables a, b, and c.
b(6a-8) if you are factoring
That's an equation in which b = -1
10a - 10 b
4(a + 2b - 4c)
4(2b+5)
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.)
8b = -65 so b = -8.125
8b = e - 12n, possibly.
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
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
-2
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
If you mean 2a8b - 5 = x and a2b = 5, then: 2(54) - 5 = x x = 1350 - 5 x = 1345
