solve the system of equation. 4x - 3y equals 14 y equals -3x plus 4 and another following up 4x - 3 equals 8 2x plus 5y equals 9 thatnk u for the help
You should begin learning algebra by learning how to write the equations. Does your computer not have +, - and = signs? If so, use them.
You have two variables so there should be two equations, yet I see the word "equals" four times. I have no idea what the equations are supposed to be.
i said another following up as in same question but different equation and kyle doesnt have +, - and = .so either answer the question with out any comment or if u don't know the ans. move on. i think its silly for us talking on a homework website get over it and go on.

To solve the system of equations step by step, let's address each set of equations separately.
First Set of Equations:
1. 4x - 3y = 14
2. y = -3x + 4
To start, we can substitute the value of y from equation 2 into equation 1 since both equations involve y.
1. 4x - 3(-3x + 4) = 14
2. 4x + 9x - 12 = 14
3. 13x - 12 = 14
4. 13x = 14 + 12
5. 13x = 26
6. x = 26 / 13
7. x = 2
Now that we have the value of x, we can substitute it back into equation 2 to find the value of y.
1. y = -3(2) + 4
2. y = -6 + 4
3. y = -2
So, the solution to the first set of equations is x = 2 and y = -2.
Second Set of Equations:
1. 4x - 3 = 8
2. 2x + 5y = 9
For the first equation, we can solve for x directly:
1. 4x - 3 = 8
2. 4x = 8 + 3
3. 4x = 11
4. x = 11 / 4
Now that we have the value of x, we can substitute it into the second equation to solve for y:
1. 2(11/4) + 5y = 9
2. 11/2 + 5y = 9
3. 5y = 9 - 11/2
4. 5y = 18/2 - 11/2
5. 5y = 7/2
6. y = 7/10
So, the solution to the second set of equations is x = 11/4 and y = 7/10.
To summarize:
For the first set of equations: x = 2 and y = -2.
For the second set of equations: x = 11/4 and y = 7/10.
