The first one is 2 the second one is 3
First distribute the 3 into 4v-1 which will result in:
12v-3-8v=17
then add/subtract your v values, so 12v-8v, which leaves:
4v-3=17
then add 3 to both sides, which cancels it out on the left side, leaving:
4v=17+3 simplified to 4v=20
next divide both sides by 4, which cancels out the 4 on the left side, leaving:
v=20/4 simplified to v=5
Good luck!
So what you do is you multiply 11 by 16 because 1pound equals 16 ounces. When you do 11 *16 you will get the answer!
Im actually learning this myself atm, The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution is a method of solving systems of equations by removing all but one of the variables in one of the equations and then solving that equation. Elimination is another way to solve systems of equations by rewriting one of the equations in terms of only one variable. The elimination method achieves this by adding or subtracting equations from each other in order to cancel out one of the variables. <span>Augmented matrices can also be used to solve systems of equations. The augmented matrix consists of rows for each equation, columns for each variable, and an augmented column that contains the constant term on the other side of the equation. For example, the augmented matrix for the system of equations 2x + y = 4, 2x - y = 0 is [[2 1], [2 -1]...[4, 0]], Good luck!</span>
Let's work backwards.
The answer will be in the form (x+a)^2 for any real number a
Now the expansion will be x^2+2ax+a^2.
We can see just from this that 2a=5/4
a=5/8
The result binomial should be x+5/8
Resulting binomial squared expansion should be x^2+5/4x+25/64
The term we need to add will be 25/64
