Question

if x=2;y=2 is the solution the equation 5x +2y +9=a. find the value of a.
​

Answer 1

Answer:

Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value.
