Step-by-step explanation:
They are equal because if you make 4/5 into a denominator of 10 it is 8/10
Answer:
The solution is (-3, 10.8)
Step-by-step explanation:
While it's rather obvious that you want to solve this system of linear equations, you should share that instruction when you post the problem.
To solve this system using elimination by addition and subtraction, combine the two equations as shown below (to eliminate y):
-0.18x + y = -6.54
-2.8x - y = -2.4
--------------------------
-2.98x = -8.94
Dividing both sides by -2.98, to isolate x, yields: x = -8.94 / (-2.98) = -3.
Then x = 3. Find y from -2.8x - y = -2.4: -2.8x + 2.4 = y, and here,
y = -2.8(-3) + 2.4 = 8.4 + 2.4 = 10.8
Then the solution is (-3, 10.8)
