Which choice is the most efficient first step to solve this set of equations?

Option b) is correct

3x+4(2x+4)=17  Substitute (2x+4) for y in the second equation

Step-by-step explanation:

Given Equations are

and

To solve the given equations we have to find the value of

x and y values.

Here y value is given so that we can substitute  y=3x+4 value  in second equation

ie., Substitute equation (1) in (2) equation we can easily get x value.

Therefore  substitute (2x+4) for y in the second equation we get

3x+4(2x+4)=17

Option b) is correct

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

the answer to your question a or b but i am pretty sure it is b. i hope this : )
