Solve x and y simultaneously
Webx + y = 7 2x + y + 3z = 32 2y + z = 13 I know that I need to combine the above 3 equations into 2 other equations, for example, if I combine (counting down) 1 + 2 I'd get. 3x + 2y + 3z = 32 And combing 2 with 3 I'd get . 2x + 3y + 4z = 45 Which is fine, and I understand. It's the next steps I have trouble understanding. WebFor -6x+3y=-18, solve for y by adding 6x to both sides, and you get 3y = 6x + 18. Divide all by 3 and your first graphable equation is y=2x+6. Now you have to convert the other equation,-3x+4y=6. Add 3x to both sides and end up with 4y=3x+6. Divide out by 4, and your second equation should equal y=3/4x+1.5.

WebSep 16, 2024 · A real number only carries one piece of information: its location on the number line. So when you add two complex numbers, you need to keep track of the real parts and the imaginary parts separately. In your case, a + b = 4 and − 2 a − 3 b = − 6. So a = 6 and b = − 2. In most cases, it's actually better to think of complex numbers as ... WebFree Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step
WebAdd a comment. 1. Another approach consists in adding the two ODEs : d y + d x d t = x + y + 2 e t = d u d t = u + 2 e t where u = y + x. This first order linear ODE is easy to solve : u = 2 t e t + c 1 e t → y = − x + 2 t e t + c 1 e t. Puting it into the first ODE : d x d t = 3 x − 2 t e t − c 1 e t.
