solution
Step-by-step explanation:
so the solution is this first multiply the numbers with out the decimal point and then count and add the decimal point.
Answer:
(-4, -1) (see below)
Step-by-step explanation:
Substitution means that you actually replace, or "substitute," the value of the variable in.
Here, y = -1, so -3x - 8y = 20 can be written as:
-3x - 8 (-1) = 20
We can now solve for x:
-3x + 8 = 20
-3x = 12
x = -4
Putting this into (x, y) format equals:
(-4, -1)
I think the answer is (2,17) as you let the equations equal one another (as they both equal y)
6x + 5 = 4x + 9
2x + 5 = 9
2x = 4
x = 2
The answer is: B) -3
In the first set of brackets the sum is -5 and in the second set the sum is 2.
-5+2=-3
