Step-by-step explanation:
I'm going to reorder the left-hand side. Multiplication is commutative.
Since the bases are the same in and the operation is multiplication, I'm going to add the exponents giving me:
So this implies we have two equations to solve:
and
So the first equation can be solved by dividing both sides by 4 giving you .
The second equation can be solved by subtracting 2 on both sides giving you .
Answer:
Step-by-step explanation:
Hello,
Touchdown is 7 points, field goals is 3 points
Let's note a the number of touchdowns and b the number of field goals, we can write
(1) a + b = 80
(2) 7a + 3b = 516
(2) - 3*(1) gives
7a + 3b - 3(a + b) = 516 - 3*80
<=> 7a + 3b -3a - 3b = 516 - 240 = 276
<=> 4a = 276
<=>
And then from (1) b = 80 - 69 = 11
Hope this helps
