Step-by-step explanation:
−7(−1+7k)−3(8k−1)
Distribute:
=(−7)(−1)+(−7)(7k)+(−3)(8k)+(−3)(−1)
=7+−49k+−24k+3
Combine Like Terms:
=7+−49k+−24k+3
=(−49k+−24k)+(7+3)
=−73k+10
Answer:
=−73k+10
<span>x + 3y = −1
2x + 2y = 6
</span><span>x + 3y = −1
x +3y -3y = -1 +3y
x= -1 +3y
2x + 2y =6
2(-1 - 3y) + 2y = 6
-2 -6y + 2y = 6
-2 -4y =6
-2+2 -4y = 6+2
-4y = 8
-4y/-4= 8/-4
y = -2
</span><span>2x + 2y = 6
</span><span>2x + 2(-2) = 6
2x + -4 = 6
2x -4 +4 = 6+4
2x = 10
2x/2 = 10/2
x = 5
Check
</span>
<span>2x + 2y = 6
2(5) + 2(-2) = 6
10 + -4 = 6
6 = 6
So the answer is (5,2)
