Y= 3 -x                         (1)

3x + 4y = 1                  (2)

Substitute (1) for y in (2)

3x + 4(3 - x) = 1

Expand, simplify and then solve for x

3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11

x = 11

Answer:

The required value of x = 11

Step-by-step explanation:

The system of equations are given to be :

y = 3 - x .......(1)

3x + 4y = 1 ......(2)

We need to find the value of x by solving these two given system of equations

So, To solve the given equations : Putting value of y from equation (1) into equation (2)

⇒ 3x + 4y = 1

⇒ 3x + 4(3 - x) = 1

⇒ 3x + 12 - 4x = 1

⇒ -x = 1 - 12

⇒ -x = -11

⇒ x = 11

Thus, The required value of x = 11

M&lt;1=115<br> M&lt;2<br> Could y’all give answers for all though
Makovka662 [10]

Answer:

1) m<2 = 115°

2) m<5 = 83°

3) m<8 = 45°

4) m<4 = 137°

Step-by-step explanation:

When two lines cross over each other, creating four angles, the opposite angles are equal.

So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.

Similarly, in question two, <5 = <6 = 84°.

In question three, <8 = <9 = 45°.

and in question four, <3 = <4 =137°.
