Answer:

5 {x}^{2}  - 2x + 3x = 9 {x}^{2}  + 9x \\ 5 {x}^{2}  + x = 9 {x}^{2}  + 9x \\ 5 {x}^{2}  - 9 {x}^{2}  = 9x - x \\  - 4 {x}^{2}  = 8x \\  - 4x = 8 \\ x =  \frac{ - 8}{4}  =  - 2 \\ x =  - 2 \\ thank \: you

NEED HELP!!!<br> Find the value of X and Y
Alex777 [14]

Answer:

x = 2

y = 152°

Step-by-step explanation:

✔️9x + 10 = 15x - 2 (corresponding angles theorem)

Collect like terms

9x - 15x = -10 - 2

-6x = -12

Divide both sides by -6

x = -12/-6

x = 2

✔️y + (15x - 2) = 180° (same-side interior angle theorem)

Plug in the value of x

y + (15*2 - 2) = 180

y + 28 = 180

y = 180 - 28

y = 152
