What is the solution to the pair of equations?
y = 7x − 9
y = 3x − 1

x = 2

Concept:

There are three general ways to solve systems of equations:

Here, we are going to use the method of substitution because [y] is isolated onto the left-hand side.

Solve:

Given information

y = 7x - 9

y = 3x - 1

Combine both equations by substitution

7x - 9 = 3x - 1

Subtract 3x on both sides

7x - 9 - 3x = 3x - 1 - 3x

4x - 9 = -1

Add 9 on both sides

4x - 9 + 9 = -1 + 9

4x = 8

Divide 4 on both sides

4x / 4 = 8 / 4

Hope this helps!! :)

Please let me know if you have any questions

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
