Answer:
The solution is (3,2)
Step-by-step explanation:
x - y = 1 →equation 1
-x + 3y = 3 →equation 2
by elimination method,
x - y = 1
-x + 3y = 3
-----------------
0 + 2y = 4
2y = 4
y = 4/2
y = 2
substitute y=2 in equation 1
x - y = 1
x - 2 = 1
x = 1 + 2
x = 3
∴(3,2) is the solution
4x - 3y = 51, when x = 15
Plug in 15 for x.
4(15) - 3y = 51
Simplify.
60 - 3y = 51
Subtract 60 from both sides.
-3y = 51 - 60
Simplify.
-3y = -9
Divide both sides by -3.
y = -9/-3
Simplify.
y = 3
