Question
Solve each system of equations using the addition method. $0.2 x-0.5 y=-0.4$$-0.3 x+0.4 y=-0.1$
Step 1
In this case, we can multiply the first equation by 3 and the second equation by 2 to make the coefficients of y the same. First equation * 3: (0.2x - 0.5y) * 3 = -0.4 * 3 0.6x - 1.5y = -1.2 Second equation * 2: (-0.3x + 0.4y) * 2 = -0.1 * 2 -0.6x + 0.8y = -0.2 Show more…
