solve the system of equations:4x - 3y equals 14 and y equals -3x plus 4 i think its either 1(4,10) (2,2)
Since 4x - 3y = 14 and y = -3x + 4,
4x - 3(-3x +4) = 14
13 x = 26
x = 2
I don't agree with any of your y values. What is the 1 by itself supposed to represent?
drwls sorry its suppose to be written like this 1( -4, -10) ,(2,2) the one but when i did the equation agin i so confused that i got another answer it could also be (5,2)
To solve the system of equations:
1) Start by rewriting the second equation in terms of y:
y = -3x + 4
2) Substitute this expression for y in the first equation:
4x - 3(-3x + 4) = 14
3) Simplify the equation:
4x + 9x - 12 = 14
13x - 12 = 14
4) Add 12 to both sides of the equation:
13x = 26
5) Divide both sides of the equation by 13 to solve for x:
x = 2
6) Substitute this value of x back into one of the original equations to solve for y. Let's use the second equation:
y = -3(2) + 4
y = -6 + 4
y = -2
So the solution to the system of equations is x = 2, y = -2. Therefore, the correct answer is (2, -2).
