Help please will give brainlist Find x+y

Leno4ka [110]

Answer:

Step-by-step explanation:

2y-5 and 95 are vertical angles so they are equal

$2y - 5 = 95$

$2y = 100$

$y = 50$

3x and 144 form a linear pair angle so

$3x + 144 = 180$

$3x = 36$

$x = 12$

x=12 and y=50 so

$12 + 50 = 62$

9x-8(x-6)=52 what is the answer

Effectus [21]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

9x - 8(x - 6) = 52

Step 2: Solve for x

Distribute -8: 9x - 8x + 48 = 52
Combine like terms: x + 48 = 52
Subtract 48 on both sides: x = 4

Step 3: Check

Plug in x to verify it's a solution.

9(4) - 8(4 - 6) = 52

36 - 8(-2) = 52

36 + 16 = 52

52 = 52
