Answer:

1. 2x+2-(2x-14)=5x+2

0x+16=5x+2

16=5x+2

14=5x

14/5=x or 2.8=x

2. 2x+10-(-2x+7)=-7x+14

4x+3=-7x+14

11x+3=14

11x=11

x=1

1) x=2.8

2) x=1

Step-By-Step:

Q1) 2x + 2 - (2x - 14) = 5x + 2

Simply the expression

2x+2-2x+14=5x+2

collect like terms

(2x-2x) + (2+14) = 5x+2

simplify

16= 5x+2

swap sides

5x+2=16

-2 -2

5x=16-2

5x=14

to get x on its own we divide each side by 5 so

5x=14

÷5 ÷5

x= 2.8

Q2) 2x + 10 - (-2x + 7) = -7x + 14

Simply the expression

2x+10+2x-7= -7+14

collect like terms

(2x+2x)+(10-7)= -7+14

simplify

4x+3=7

-3 -3

4x+3-3=7-3

simplify

4x=7-3

4x=4

to get x on its own divide each side by 4 so...

4x=4

÷4 ÷4

x=1

Hope this helped- have a good day bro cya)

Answer:

Option 2: m∠1 = 147°, m∠2 = 80°, m∠3 = 148°

Step-by-step explanation:

Step 1: Consider triangle ABC from the picture attached below.

Lets find angle x

x + 47 + 33 = 180 (because all angles of a triangle are equal to 180°)

x = 100°

Angle x = Angle y = 100° (because vertically opposite angles are equal)

Step 2: Find angle 2

Angle 2 = 180 - angle x (because angle on a straight line is 180°)

Angle 2 = 180 - 100

Angle 2 = 80°

Step 3: Find angle z

48 + y + z = 180° (because all angles of a triangle are equal to 180°)

z = 32°

Angle 3 = 180 - angle z (because angle on a straight line is 180°)

Angle 3 = 180 - 32

Angle 3 = 148°

Step 4: Find angle 1

Angle 1 = 180 - 33 (because angle on a straight line is 180°)

Angle 1 = 147°

Therefore m∠1 = 147°, m∠2 = 80°, m∠3 = 148°

Option 2 is correct

Solve the system of equations using substitution

Sauron [17]

y = −2x + 1

4x + 2y = −1

Replace Y in the second equation with the value of Y in the first one.

4x + 2(-2x +1) = -1

Distributive Property:

4x + -4x + 2 = -1

Combine like terms:

2 = -1 which is not true, so there are no solutions.
