Answer:
- 120x + 288y
Step-by-step explanation:
Begin by summing the 2 expressions
- 2(10x + 3y) - 5(6y - 7x) ← distribute parenthesis
= - 20x - 6y - 30y + 35x ← collect like terms
= 15x - 36y
Now multiply the result by - 8
- 8(15x - 36y) ← distribute
= - 120x + 288y
Answer:
Step-by-step explanation:
-2(10x + 3y)
-20x -6y [-2 multiplied by 10x = 20x, negative + positive = negative]
-5(6y -7x)
-30y + 35x
-20x -6y -30y +35x
35x - 20x -30y -6y
<em><u>15x - 36y</u></em>
<em><u /></em>
<em><u>Answer = 15x -36y</u></em>
