Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).
Answer:
3x-4=2x+1 the answer is x=5
3x-4-2x=2x+1-2x the answer is x=5
x-4=1 the answer is x=5
x-4+4=1-4 the answer is x=-3
x=-3 is already the answer
Step-by-step explanation:
3x-4=2x+1
=3x-2x=1+4
=1x=5
=1x/1=5/1
=x=5
3x-4-2x=2x+1-2x
=3x-2x-2x+2x=1+4
=1x=5
=1x/1=5/1
=x=5
Answer:Therefore you need the trig function that contains both the OPPOSITE and the HYPOTENUSE, which would be SINE, since sin = OPPOSITE / HYPOTENUSE.
Step-by-step explanation:
Step 1: Determine which trigonometric ratio to use.
Step 2: Create an equation using the trig ratio sine and solve for the unknown side.
