I need to know the solution to this

Alex73 [517]

There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate

Look at equation 1, $-2x+y=10$ this can quite easily be manipulated to show $y=10+2x$ .

Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one $4x-y=-14 \Rightarrow 4x-(10+2x)=-14$ which can then be solved for x since there is only one variable $4x-10-2x=-14 \Rightarrow 2x=-4 \Rightarrow x=-2$ and then with our x solution we can work out our y solution by using the equation we manipulated $y=10+2x = 10+(2 \times -2) = 10-4=6$ .

So the solution to these equations is x=-2 when y=6

Jake and amber worm at McDonald's they each earn $8 per hour jake works three more hours then amber if jake and amber made a tot

Nadya [2.5K]

Answer:

9 hours

Step-by-step explanation:

Set up the equations: x is the amount of hours Amber worked and y is the hours Jake worked

8x + 8y = 120

y = 3 + x

Substitute the second equation into the first

8x + 8(3+x) = 120

Distribute

8x + 24 + 8x = 120

Combine like-terms

16x + 24 = 120

Subtract 24 on both sides

16x = 96

Divide 16 on both sides

x = 6 (hours Amber worked)

Plug in this x-value into on of the two equations. I will use the second

y = 3 + 6

y = 9
