Question

Solve for x and y in each of the following math equations use either method substitution or elimination for 1,2,3 questions.

1.) 4u + (5u + 4) = t +1

     2t + 9 = 14

2.) 90 + 1/a = 6b + (-10)

     100 + a = (1/2) (b)

3.) 3x + 9Y = 14x

     9+ (y+12**1) = b

     b+ 40 = b+20

4.) Which method do you prefer and why elimination or substitution?
