Question

solve the equation

Answer 1

5x + 2y = 19 x - 2y = -1

Answer 2

solve for x and y

Answer 3

x=\[2y \div 7\]

Answer 4

wait that's wrong

Answer 5

5x + 2y = 19
x - 2y = -1
------------add
6x = 18 -- divide both sides by 6
x = 3

now sub 3 in for x in either of the original equations to find y
x - 2y = -1
3 - 2y = -1
-2y = -1 - 3
-2y = -4
y = 2

check...
5x + 2y = 19
5(3) + 2(2) = 19
15 + 4 = 19
19 = 19 (correct)

so x = 3 and y = 2
any questions at all ??
