First answer: x = 3

How?

3x - 7 = 2

3x = 2 + 7

3x = 9

x = 9/3

x = 3

Second Answer:= x=5

How?

3 + 2x - (x + 1) = 3x - 6

-3x + 2x - x = -6 - 3 - 1

-2x = -10

x = 5

Equation #1: 7x =
21.25
Equation #2: 3(y - 2) = 12

Answers

Equation 1:
7x = 21.25 or
21.25/7 = x
21.25/7 = 3.03571429
so x = 3.03(just round to whatever place u need).

Equation 2:
3(y - 2) = 12 or
3(x)=12
x=4
so y - 2 has to equal 4
and 6-2 = 4 therefore
y = 6.

You find the measure of angle BEC, by adding angle B and angle C which is 43+90, and then subtract that from 180 and get 180-(43+90). Then you take the measure of angle BEC (which is the same as AEB), take AEB and A which is 90 degrees and add those together. Then you take that and subtract it from 180, which is 180-(AEB+90)

Find the solution to the system. Write your solution as an ordered pair (x,y)
with no spaces, no solution, or infinitely many. 2x+6y=56 and 4x+12y=24 *

Answers

Answer:

No solution is your answer ( I do not know who you are supposed to type it out, but there are 0 solutions for this system).

Step-by-step explanation:

Key skills needed: Systems, Elimination, Recognizing Solutions

We are given:     2x + 6y = 56

                    and 4x + 12y = 24

To find x and y, we can use elimination. We can multiply the first one by -2 and both equations to eliminate x.

-2(2x+6y) = 56(-2) (Tip: Use distributive property

--> -2(2x)  = -4x

--> -2(6y) = -12y

--> 56(-2) = -112

This means that:    -4x - 12y = -112

Add this one to:   + 4x + 12y = 24

                              ----------------------

You will get -->       0 = -88

0 does not equal -88 so there is no solution for this!
