Answer:

Symmetric property of equality

Step-by-step explanation:

The symmetric property allows you to swap sides of the equation and be assured the equation is still true:

If x = y, then y = x — symmetric property.

Answer:

the symmetric property of equality

Step-by-step explanation:

If 5 = x + 2, then x + 2 = 5. both have an equation so it represents an equation.

Reflexive property of equality states that  a=a

Symmetric property of equality states that

If c=a+b then a+b= c

In the given statement

If 5=x+2 then x+2=5

The given statement represents the symmetric property of equality

What are the values of x and y if this equation is true?<br><br> 22(x + yi) + (28 + 4i) 72 – 62i
ASHA 777 [7]

Answer:

x = 2

y = -3

Step-by-step explanation:

The given equation is,

22(x + yi) + (28 + 4i) = 72 - 62i

By solving this equation further,

22x + 22yi + 28 + 4i = 72 - 62i

(22x + 28) + (22y + 4)i = 72 - 62i

Now both the sides of the equation is in the form of complex number,

By comparing real and imaginary parts given on both the sides,

22x + 28 = 72

22x = 72 - 28

22x = 44

x = 2

22y + 4 = -62

22y = -62 - 4

22y = -66

y = -3

Therefore, x = 2 and y = -3 are the values for which the given equation is true.

(05.02 MC) A system of equations is shown below: 4x = −3y + 17 3x − 4y = −6 What is the solution to this system of equations? (−
aliina [53]
4x=-3y+17 becomes 4x+3y=17

4x+3y=17
3x-4y=-6

alrighty

elimination

muliply first equation by 4 and 2nd by 3 and add them
16x+12y=68
9x-12y=-18
add them

25x+0y=50
25x=50
idivide both sides by 25
x=2

sub back

3x-4y=-6
3(2)-4y=-6
6-4y=-6
-4y=-12
y=3
