Answer: 14.2 - 5a
Work: I just did "CLT" of "Combine Like Terms". I did 8 + 6.2 First because 8 is first, then I did 4a - 9a which is -5a, and I combined them, and got the answer. I hope this helps, and stay safe! :)
Answer:
40% of 25 is <u>10</u>
Step-by-step explanation:
The ordered pair (- 3, 1 ) is a solution to the second equation because it makes the second equation true
To test , substitute the coordinates of (- 3, 1) into the equations and if both sides are true then it is a solution to the equation.
x - 4y = - 3 - 4 = - 7 ≠ 6 ← not true
(3 × - 3) + 1 = - 9 + 1 = - 8 ← true
Thus (- 3, 1 ) is a solution to the second equation
