10Step 1: Subtract x from both sides.3x−4−x=x−x2x−4=0Step 2: Add 4 to both sides.2x−4+4=0+42x=4Step 3: Divide both sides by 2.2x2=42x=2

2)Step 1: Subtract x from both sides.2x−4−x=x−xx−4=0Step 2: Add 4 to both sides.x−4+4=0+4x=4

Well, lets solve by combing like terms.
For the first it would be:
2x=4
The second would be:
x=4
So for #1 x=2 and #2 x=4

Hope this helps!

Find the measures of the interior angles of the triangle.

MrMuchimi

Answer:

∠ A = 59°, ∠ B = 48° , ∠ C = 73°

Step-by-step explanation:

The interior angles of a triangle sum to 180°

sum the 3 angles and equate to 180

x + x - 11 + 73 = 180

2x + 62 = 180 ( subtract 62 from both sides )

2x = 118 ( divide both sides by 2 )

x = 59

Then

∠ A = x = 59°

∠ B = x - 11 = 59 - 11 = 48°

∠ C = 73°

Help please solve for x

Y_Kistochka [10]

Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)

Step-by-step explanation:

Linear pairs of angles sum to 180.

37+(3x+2) =180

Combine like terms

39+ 3x = 180

Subtract 39 from both sides

3x = 141

Divide both sides by 3

x= 47
