Can someone please help me solve task e)?

If someone could solve the problem e for me with calculation steps that would be great no AI can do that and unfortunately my secondary school teacher can't either but it's no use I have to be able to do that

5a)

b from g1

straight: y = gradient x + y-axis cutting point
y = m*x + b

4.5 = 3/4 * 4 + b

4.5 – 3 = b

y = 3/4 x + 3/2

.

.

5e)

in two steps

-14

-3y = 3.75x – 7 – 14

-3y = 3.75x – 21

share by -3

y = -1.25x + 7

.

equation with g1 from 5a)

3/4 x + 3/2 = -1.25x + 7

3/4 x + 1.25 x = 7 – 3/2

3/4 x + 5/4 x = 5.5

8/4 x = 5.5

2x = 5.5

x = 2.75

and y?

3/4 * 2.75 + 3/2 =

3/4 * 9/4 + 6/4 =

27/16 + 6/4 =

27/16 + 24/16 =

51/16

D is ( 9/4 ///// 51/16 )

.

PS For primary school, it’s too heavy. No wonder that so many have to leave without a conclusion

one straight line is 14-3y=3.75x-7, the other y=0.25x+4

For example, it is possible to insert the second at y into the first and then to dissolve after x, then the x coordinate of D. y is then inserted by inserting x into the simpler straight line equation

second inserted into first:14-3(0.25x+4)=3.75x-7
multiplicate, summarize and dissolve after x

Convert one of the equations to one variable and then to the other. Then determine the x value and finally insert it into one of the functions for the y value

The straight line is in a somewhat unusual form. You bring it to the normal form y= ax +b.

Then you think what it means is that two straight lines intersect. There, both the x value and the y value are the same.

Since you now have both straight lines in the beautiful shape, it is easy to put them over the y value equal and to calculate the appropriate x value.

I explained it hairy. What do you not understand about my explanation?

Try to read them exactly ..
