Solve by using substitution
WebHere is one approach (others may also be possible, but we will use your hint). We are given: (1) d y d x = 2 y x + x 3 y + x tan y x 2. Lets choose the substitution: (2) z = y x 2 → y = x 2 z. Differentiating ( 2) yields: (3) d y d x = 2 x z + x 2 d z d x. Substituting ( 2) into ( 1) yields: (4) d y d x = 2 x 2 z x + x 3 x 2 z + x tan x 2 z x ...

WebJul 27, 2024 · Solving for y in the first equation, you get. Put that into the second equation and solve for z following these steps: Substitute in for y: Multiply each term by 11 to get rid of the fraction: 16 (19 z + 41) – 253 z = 605. Simplify: 304 z + 656 – 253 z = 605, which becomes 51 z = –51. Divide each side by 51: z = –1. WebIXL - Solve a system of equations using substitution (Algebra 1 practice) Learning. Assessment.
