Question: 2{4x - 3(x + 5) + 10} + 3(x - 2)
Steps
1. Expand 4x - 3(x + 5) + 10 = x - 5
= 2(x - 5) + 3(x - 2)
2. Expand 2(x - 5) = 2x - 10
= 2x - 10 + 3(x - 2)
3. Expand 3(x - 2) = 3x - 6
= 2x - 10 + 3x - 6
4. Then, simplify:
Add 2x + 3x = 5x
Add -10 - 6 = -16
5. Plug it in:
5x - 16 <-------------- Answer
Hope this helped!!!!
Answer:
yes
Step-by-step explanation:
There are two ways to solve system of equations.
1) substitution method
2) elimination method
4x - y = -6
x - 2y = -5
For thus problem, i'll be using the substitute method.
So, using the equation x - 2y = -5:
Solve for "x" by adding 2y to both sides of the equation.
x = 2y - 5
Now we know what "x" is, we can substitute it in the other equation.
4x - y = -6
4(2y - 5) - y = -6
8y - 20 - y = -6
7y - 20 = -6
7y = 14
y = 2
We now know the numerical value of y. So, all we have to do is plug in y into either system of equation to solve for the numerical value of x.
4x - 2 = -6 x - 2y = -5
4x = -4 x - 2(2) = -5
x = -1 x - 4 = -5
x = -1
The solution is (-1, 2) where x equals -1 and y equals 2.
Ax/c + b - d = e
ax/c = e + d - b
ax = c*(<span>e + d - b)
x = </span>c*(<span>e + d - b)/a
x = </span> c(<span>e + d - b)/a</span>
Answer:
-131,072
Step-by-step explanation:
a(n)=an-1*-4
128=a(4)
128*-4*4*-4*-4*4=-131072.
