muneepenne, you are a disgrace! Every one of your responses starts with an insult, and YOU need to learn how to write. Your spelling is atrocious. You don't even spell the words correctly when they are already written in the problem statement. As for this one, I see two equations, why can't you? Remember, people came here for help precisely because they don't know how to solve the problems. They don't need your garbage thrown at them.

Answer 2

what is the ordered pairs for thie=s equation –3x + 2y = 2   7x – 3y = 7

Solving simultaneous equations is usually done by making necessary
adjustments to one or both, then adding or subtracting the equations
to eliminate one of the unknowns, either x or y. We will get rid of the
y terms by multiplying equation 1 by 3, and multiplying equation 2 by 2.

3 * (–3x + 2y) = 3 * 2                   -9x + 6y =  6
2 * (7x – 3y)   = 2 * 7                   14x - 6y = 14
                                                --------------------
Add them ---->                             5x        = 20
5x = 20
x = 4

We substitute that value in equation 2 to solve for y.

(7 * 4) – 3y = 7
28 - 3y = 7
-3y = 7 - 28 = -21
y = -21 / -3 = 7

Verify by substituting both x and y values into equation 1.

(–3 * 4) + (2 * 7) = 2
-12 + 14 = 2
2 = 2

The answer: (4, 7)
