Say your function is
f(x) = 2x + 3
If f(x) is 2 & you want to find x, replace f(x) with 2:
2=2x+3
And solve for x:
-1=2x
x=-1/2
Hope this helps!

2 5/8 ×3 1/7 What's the answer for this ?

nikdorinn [45]

Answer:

$8 \frac{1}{4}$

Step-by-step explanation:

Let us solve

$2 \frac{5}{8} \times 3 \frac{1}{7} \\ \frac{21}{8} \times \frac{22}{7} \\ \frac{462}{56} \\ \frac{462 \div 2}{56 \div 2} \\ \frac{231}{28} \\ \frac{231 \div 7}{28 \div 7} \\ \frac{33}{4} \\ 8 \frac{1}{4}$

hope this helps you.

Please let me know if you have another questions :-)

Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.

ycow [4]

This involves quite a lot of arithmetic to do manually.

The first thing you do is to make the first number in row 2 = to 0.

This is done by R2 = -3/2 R1 + R2

so the matrix becomes

( 2 1 1) ( -3 )

( 0 -13/2 3/2) (1/2 )

(5 -1 2) (-2)

Next step is to make the 5 in row 5 = 0

then the -1 must become zero

You aim for the form

( 1 0 0) (x)

(0 1 0) (y)

(0 0 1) ( z)

x , y and z will be the required solutions.
