Solve each system of linear equations by substitution.3x - 2y = 9 y = 2x - 7 Pease show all steps
Answers
3x-2y=9 will be 3x-9=2y and (3x)/2-9/2=y
2) y=2x-7
if you mean the intersection , so y=y (3x)/2-9/2=2x-7 1,5x-4,5=2x-7 -4,5+7=2x-1,5x 2,5=0,5x x=2,5/0,5 x=5 is the answer
Solve linear system using substitution
y=6-2x 7x-y=3

How can I find two numbers whose sum is 38 and whose difference is 14
Answers
assume 1st num is x and 2nd num is y you want x+y = 38 and x-y = 14 by solving those two equations we get x = 26 & y= 12 so , the numbers is 12 & 26
How do I do these questions?
