Solve for x and y in the following simultaneous equations: x+y=17 x−y=3 相关知识点: 试题来源: 解析x=10 y=7 Since x+y=17, this implies that x=17−y. Together with x−y=3, we obtain: 17−y−y=3→17−2y=3→2y=14→y=7 This implies that x=17−7=10反馈...
Putting (1)/(sqrtx ) = u and (1)/(sqrty) = v , the given equations become 2u + 3v = 2 " "… (i) 4u - 9v = - 1 " " … (ii) Multiplying (i) by 3 and adding the result with (ii), we get 6u + 4u = 6- 1
Write out the two equations that have the two variables you want to solve. For this example, we will find the value for "x" and "y" in the two equations "3x + y = 2" and "x + 5y = 20" Step 2 Solve for one of the variables in on one of the equations. For this example, ...
