Hey friend here is your answer
Answer:
15
Step-by-step explanation:
The answer is 15 because you have to solve the equation which gets you 15
first cancel out the x
Then you will get ur answer
HOPE THIS HELP:)
STAY SAFE
you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 ) units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x

Answer:

Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
<em>Verify each case</em>
Part 1) we have

solve for x




Part 2) we have

Multiply both sides by -1 and rearrange the terms on the left side to get

This expression is the same that the expression in Part 1)
That means, that the equations Part 1) and Part 2) are equivalent
therefore

Part 3) we have

Remember that

This expression is the same that the expression in Part 1)
That means, that the equations Part 1) and Part 3) are equivalent
therefore

Part 4) we have

This equation is not equivalent to the other three, because some terms are multiplied by -8/7 and others are not. When different things are done on either side of the equal sign, it changes the equation, resulting in a different solution
