Question

still having trouble on these and the steps ,

x+y=5
3x+2y=11

Answer 1

solve simultaneously?

Answer 2

Do you know how to use substitution?

Answer 3

x + y = 5
-y
x = 5 - y

Substitute the value of x into the second equation:
3x+2y=11
3(5 - y) + 2y = 11
15 - 3y + 2y = 11
combine like terms:
15 - y = 11
Solve for y:
15 - y = 11
-15
-y = -4
/-1
y = 4

x+y=5
x + 4 = 5
solve for x:
x + 4 = 5
-4
x = 1

So x = 1 & y = -4
(1,-4)

Answer 4

Hope this helps!
