X=-1 and y=3
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.
Answer:
x = 0
Step-by-step explanation:
The distributive property of multiplication states that a(b - c) = a(b) - a(c). We can apply that to the given equation.
3(2 - x) = 6
3(2) - 3(x) = 6 (Apply distributive property on LHS)
6 - 3x = 6 (Simplify LHS)
6 - 6 - 3x = 6 - 6 (Subtract 6 from both sides)
-3x = 0 (Simplify both sides)
(Divide both sides by -3)
x = 0 (Simplify)
Hope this helps!
