Multiply 2x-2y=10 by 2,
4x-4y=20,
given:4x-5y=17
y=3
pluck it in
2x-6=10
move the 6 to the right
2x=16
divide
x=8
y=3
Answer:
d) 2x(4x + 2)
Step-by-step explanation:
a) 4(2x + 1) = 8x + 4
b) 1/2(16x + 8) = 8x + 4
c) 2(4x + 2) = 8x + 4
d) 2x(4x + 2) = 8x² + 4x

Answer:
x = 111
Step-by-step explanation:
1.) x + (x + 1) + (x + 2) = 336
2.) x + x + 1 + x + 2 = 336
3.) 3x + 3 = 336
4.) 3x = 333
4.) x = 111
Check Work:
1.) 111 + (111 + 1) + (111 +2) = 336
2.) 111 + 111 + 1 + 111 + 2 = 336
3. ) 222 + 1 + 111 + 2 = 336
4.) 222 + 114 = 336
5.) 336 = 336
Answer:
D, infinitely many solutions
Step-by-step explanation:
Let's first simplify the left side:
3/4 z - 1/4 z + 1 = 2/4 z + 1
Clearly, once you simplify the left side, it's the exact same as the right side. This is a true equation: 2/4 z + 1 = 2/4 z + 1
For any value that you put in for z, it will always be equal, no matter what.
Thus, the equation has D, infinitely many solutions.
Hope this helps!
