Answer:
x = 4
y = 1
Step-by-step explanation:
x = 3y + 1 (Multiply everything by -2)
2x + 4y = 12 (Transfer 4y to the right of the = sign)
2x = -4y + 12
-2x = -6y - 2
0 = -10y + 10
-10 = -10y
x = 3y + 1
x = 3(1) + 1
x = 3 + 1
7/10 * 1/2 = 7/20
since the equation on the left can be rewritten :
to be 5n-10 then both sides of the equation are equal
so any real number will work
