Question
Solve each system of equations using the addition method. $5 x+3 y=12$$3 x-6 y=15$
Step 1
In this case, we can multiply the first equation by 2 to make the coefficients of y additive inverses. (2)(5x + 3y) = (2)(12) 10x + 6y = 24 Now we have the system: 10x + 6y = 24 3x - 6y = 15 Show more…
