Answer:
x = 1/2
, y = 3/2
Step-by-step explanation:
Solve the following system:
{3 y + x = 5
-2 x - 4 = -5
Hint: | Choose an equation and a variable to solve for.
In the second equation, look to solve for x:
{3 y + x = 5
-2 x - 4 = -5
Hint: | Isolate terms with x to the left hand side.
Add 4 to both sides:
{3 y + x = 5
-2 x = -1
Hint: | Solve for x.
Divide both sides by -2:
{3 y + x = 5
x = 1/2
Hint: | Perform a substitution.
Substitute x = 1/2 into the first equation:
{3 y + 1/2 = 5
x = 1/2
Hint: | Choose an equation and a variable to solve for.
In the first equation, look to solve for y:
{3 y + 1/2 = 5
x = 1/2
Hint: | Isolate terms with y to the left hand side.
Subtract 1/2 from both sides:
{3 y = 9/2
x = 1/2
Hint: | Solve for y.
Divide both sides by 3:
{y = 3/2
x = 1/2
Hint: | Sort results.

Answer:
Option D is correct.
y =6
Step-by-step explanation:
Given the system of equation:
.......[1]
.......[2]
Multiply equation by 12 in [1] we get;
.......[3]
Multiply equation by 12 in [2] we get;
.......[4]
Multiply equation [3] by 5 we get;
.....[5]
Multiply equation [4] by 4 we get;
.....[6]
Subtract equation [6] from [5] to eliminate x we get;
Divide both sides by 69 we get;
x = -4
Substitute the value of x in [3] we get;
Subtract 36 from both sides we get;
Divide both sides by -8 we get;
y = 6
Therefore, the value of y is 6
