1. write the answer in the form (x, y) 2.write the answer in the form (x, y, z). 3. explain the answer to the inequality. 4. best explain question four by simplify.

1.) 3x - 4y = -5 . . . (1)
-x + 2y = 3 . . . (2)
Make the coeficient of one of the variables equal. We make the coeficient of y equal by multiplying (2) by 2.
(2) x 2 => -2x + 4y = 6 . . . (3)
Eliminate the variable by subtracting (if the signs are the same) or adding (if they have different signs), here the coefitient of y in (1) and (3) are the same but have different signs, so we add.
(1) + (3) => x = 1
Substituting x = 1 into any ot the equations gives you the value of y, we substitute into equation (2).
-1 + 2y = 3
2y = 3 + 1 = 4
y = 4/2 = 2
Writing the answer in the form of (x, y), we have (1, 2).

No i refuse to tell you the answer but the estimate is 10
