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?
