2 - 3b = 7b + 12 Let us introduce equal terms (3b - 12 in this specific case) on each side (left and right) of the equal sign, so that the 'b' term is all alone on one side of the equal sign. 2 - 3b + (3 b - 12) = 7b + 12 + (3 b - 12) -10 = 10b b = -1 =============================

(a+b)(3b+1)
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
If you mean 3b+9 = 12 then b equals 1
To simplify the expression 3b^2 - 3b, we first factor out the common factor of 3b. This gives us 3b(b - 1), where b - 1 is the simplified form of the expression. This expression represents the difference between 3 times the square of a variable b and 3 times the variable b.
In algebra, when you have the expression "3b + b," you can simplify it by combining like terms. In this case, the like terms are both terms with the variable "b." So, 3b + b is equal to 4b. This is because you are adding the coefficients (3 and 1) together while keeping the variable "b" the same.
2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b
2 - 3b = 7b + 12 Let us introduce equal terms (3b - 12 in this specific case) on each side (left and right) of the equal sign, so that the 'b' term is all alone on one side of the equal sign. 2 - 3b + (3 b - 12) = 7b + 12 + (3 b - 12) -10 = 10b b = -1 =============================

3ab - a - 3b2 + b = -3b2 + 3ab + b - a = -3b(b - a) + 1(b - a) = (1 - 3b)(b - a)
(a+b)(3b+1)
-7+3b = 4b-8 3b-4b = -8+7 -b = -1 b = 1
If you mean 3b+9 = 12 then b equals 1
Write down both equations (I'll label them (1) and (2)):(1) a = 3b - 4(2) a + b = 16Pass b to the left side of the equation (1):(1) a - 3b = -4(2) a + b = 16Multiply (1) by -1:(1) -a + 3b = 4(2) a + b = 16Add down both equations:-a + 3b + a + b = 4 + 164b = 20b = 5Replace b in (2):a + 5 = 16a = 11
The expression 3b x b can be simplified by multiplying the coefficients (numbers) and the variables separately. In this case, 3b x b simplifies to 3b^2, where b^2 represents b squared. This means you multiply the coefficient 3 by the coefficient 1 (since b can be thought of as b^1) to get 3, and you multiply the variable b by itself to get b^2.
(3b)5 = 243 b5The actual numerical value depends on the value of ' b ',and it changes instantly any time ' b ' changes.
