Answer:
Step-by-step explanation:
Plug in 16 for x. (4-16) then the answer is -12
Step-by-step explanation:
y = -6x + 10 (1)
-5x + y = -1 (2)
Sub (1) into (2)
-5x + (-6x + 10) = -1
-5x - 6x + 10 = -1
-11x = -11
-11x/-11 = -11/-11
x = 1
Sub x = 1 into (1)
y = -6(1) + 10
y = -6 + 10
y = 4
4th option is correct.
look at the picture i sent
Answer:
x = -6
Step-by-step explanation:
10x = 6x - 24
Subtract 6x from both sides.
4x = -24
Divide both sides by 4.
x = -6
Question:
Yuet solved the equation
for a.
Her steps are shown below.
1. Subtract 2b: ![6a = 12 - 2b](https://tex.z-dn.net/?f=6a%20%3D%2012%20-%202b)
2. Divide by 6: ![a = 2 - \frac{b}{3}](https://tex.z-dn.net/?f=a%20%3D%202%20-%20%5Cfrac%7Bb%7D%7B3%7D)
Answer:
In step 1 she needed to add 2b to both sides of the equation.
Step-by-step explanation:
Given:
The above steps shows how Yuet solved an equation
Required:
True statement about Yuet's work
The implication of the statement is to state what Yuet should have done instead of what she did.
In step 1, she subtracted 2b from both sides of the equation; this is wrong.
Instead of subtracting, she ought to add 2b to both sides of the equation.
The correct steps and result is as follows:
1. Add 2b: ![6a = 12 + 2b](https://tex.z-dn.net/?f=6a%20%3D%2012%20%2B%202b)
2. Divide by 6: ![a = 2 + \frac{b}{3}](https://tex.z-dn.net/?f=a%20%3D%202%20%2B%20%5Cfrac%7Bb%7D%7B3%7D)
Hence, we can conclude that in step 1 she needed to add 2b to both sides of the equation.
