How do you solve 5b squared equals 8b?
5b2 = 8b therefore 5b =8 therefore b = 1.6
4 x b-1 plus -4 plus 4b?
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
What is 4a plus 8b - 12c?
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.

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.)
What is 6(7a plus 2b) plus 8a-8b?
To simplify the expression (6(7a + 2b) + 8a - 8b), first distribute the 6: [6 \cdot 7a + 6 \cdot 2b = 42a + 12b.] Now, combine this with the remaining terms: [42a + 12b + 8a - 8b = (42a + 8a) + (12b - 8b) = 50a + 4b.] Thus, the simplified expression is (50a + 4b).
What is the answer of 23 plus 8b equals -42?

What is equivalent to e equals 8b plus 12n?
8b = e - 12n, possibly.
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
