Simplify the expression
4(b - 6) + 19 =

b = 1.25

Step-by-step explanation:

Simplifying

4(b + -6) + 19 = 0

Reorder the terms:

4(-6 + b) + 19 = 0

(-6 * 4 + b * 4) + 19 = 0

(-24 + 4b) + 19 = 0

Reorder the terms:

-24 + 19 + 4b = 0

Combine like terms: -24 + 19 = -5

-5 + 4b = 0

Solving

-5 + 4b = 0

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 4b = 0 + 5

Combine like terms: -5 + 5 = 0

0 + 4b = 0 + 5

4b = 0 + 5

Combine like terms: 0 + 5 = 5

4b = 5

Divide each side by '4'.

b = 1.25

Simplifying

b = 1.25

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
