What is the solution of the equation y=2x-7;y=5x+4
Reika [66]

Step-by-step explanation:

y = 2x - 7...(1) \\ y = 5x + 4...(2) \\ from \: equations \: (1) \: and \: (2) \\ 5x + 4 = 2x - 7 \\   \therefore \: 5x - 2x =  - 7 - 4 \\  \therefore \: 3x =  - 11\\   \huge \red{ \boxed{\therefore \: x =  -   \frac{11}{3} }}\\  substitutig \: x =  -   \frac{11}{3} in \: equation \: (1) \\ y = 2 \times (-   \frac{11}{3}) - 7 \\  \\ \therefore \: y =  -  \frac{22}{3}  - 7 \\  \\  \therefore \: y =   \frac{ - 22 - 21}{3} \\  \\  \huge \orange{ \boxed{\therefore \: y =   - \frac{ 43}{3}}}\\\\(x, \:y) = \{-   \frac{11}{3}, - \frac{ 43}{3}\} \:
