WebFeb 10, 2024 · 5. Isolate the variable. The last thing you have to do to solve for x is to isolate the variable by dividing both sides of the equation by 2, the coefficient of the x term. 2x/2 = x and 16/2 = 8, so you're left with x = 8. 6. Check your work. Plug 8 back in to the equation for x to see if you get the right answer: WebOne way you can do that is by multiplying the top equation by 5 and multiplying the bottom equation by 3 because then, you could easily cancel out the 15 (top equation) and the -15 (bottom equation) and solve the rest of the equation accordingly. >>> 5x + 3y = 12 4x - 5y = 17 5x + 15y = 12 4x - 15y = 17 5x = 12 4x = 17 9x = 29 x = ~3.22 (Then ... how alzheimer\\u0027s disease typically progresses
