X=3y+10 x=-8y-12<br><br> can u guys help me find the steps to solve this equations
Natalija [7]

Answer:

x=4, y=-2

Step-by-step explanation:

x = 3y + 10 \\ x =  - 8y -12\\ now \\ 3y  + 10 =  - 8y - 12 \\ 3y + 8y =  - 12 - 10 \\ 11y =  - 22 \\ y =  \frac{ - 22}{11}  \\ y =  - 2 \\ again \: putting \: the \: value \:of \: y \\ x = 3y + 10 \\ x = 3( - 2) + 10 \\ x =  - 6 + 10 \\ x = 4
