Match the equation with its corresponding solution for x. 4x + 7 = 35
lyudmila [28]
Are you wanting to solve for x? If so:
4x + 7 = 35
We want to isolate the variable, so subtract 7 from both sides.  You will get:
4x = 28
Now, divide each side by 4 to get X by alone. This will give you:
x = 7
I hope this helped.

Determine the value (or values) of h such that the matrix: 2 - 3 h - 6 9 5 is the augmented matrix of a consistent linear system
Verizon [17]

Answer:

In order to have a consistent linear system represented by the augmented matrix:

\left[\begin{array}{ccc}2&-3&h\\-6&9&5\end{array}\right]

the value of h must be:

h=-\frac{5}{3}

Step-by-step explanation:

A system is consistent if it has a solution, this solution can be unique or a set of infinite solutions.  

First, you take the augmented matrix and find the equivalent row echelon form using Gaussian-Jordan elimination:

To do this, you have to multiply the 1st row by 3 and add it to the 2nd row, the resulting matrix is:

\left[\begin{array}{ccc}2&-3&h\\0&0&5+3h\end{array}\right]

Now, write the system of equations:

2x_1-3x_2=h\\0x_1+0x_2=5+3h

The only way this system has a solution is if 5+3h=0, then, to satisfy this, the value of h must be:

h=-\frac{5}{3}

natita [175]
Answer: -8
Here’s why: you start by subtracting the 4 from both sides. Leaving you with
-7y= 56
Divide by -7 on both sides
-7y/-7 = y 56/-7=-8
