2x+9=3x+1 what does x equal

8 =x

Step-by-step explanation:

2x+9=3x+1

Subtract 2x from each side

2x-2x+9=3x-2x+1

9 = x+1

Subtract 1 from each side

9-1 = x+1-1

8 =x

x = 8

Step-by-step explanation:

2x + 9 = 3x + 1

Add -3x and -9 on both sides.

2x + 9 - 3x - 9= 3x + 1 - 3x - 9

2x - 3x = 1 - 9

Combine like terms.

-1x = -8

Divide both sides by -1.

-1/-1x = -8/-1

x = 8

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
