WebTo solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables. Solve the resulting equation for the ... Web`(5x + 2y)/6 = -7` => 5x - 2y = -42 ....(iv) Let us eliminate y from the given equations. The coefficients of y in the equations(iii) and (iv) are 3 and 2 respectively. The L.C.M of 3 and 2 is 6. So, we make the coefficient of y equal to 6 in the two equations. Multiplying (iii) by 2 and (iv) by 3, we get. 8x + 6y = 264 ...(v) 15x - 6x = -126 ... flux capacitor invented date
