Solve step by step and explain three math questions pls! Ill make brainliest :) 1. 13 + 4q = -2q + 12 + q
2. 2.5x - 4 + 1.2 = 3.5
3. -27 = -9y + 6y + 3

What is the solution of the systems of equations? y=2/3x+3 x=-2

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
