We can create a formula first.
X will be the unknown number
840= 357+x
-357 -357
483 = x
Hope this helps
Solving the equations by graphing requires plotting the given functions.
y=x^2-3
x-y=1
thus the plot will be as shown in the picture. The solutions are:
(-2,-1) and (2,1)
Answer:
Step-by-step explanation:
1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7
2)Subtract 7 from both sides
4x+7=39
-7 -7
4x=32
3) Divide by 8
x=8
Thus we get x=8 as answer
So reasons are
i) Distributive property
ii) Subtraction property of equality
iii) Division property of equality
Answer:
x = -5
Step-by-step explanation:
I) Substitute:
3x + 2y = -5
3x + 2(5) = -5
3x + 10 = -5
II) Solve:
3x + 10 = -5
3x = -15 (Subtract 10 from both sides)
x = -5 (Divide both sides by 3)
