-5x + 7y = 11 (1)
-5x + 3y = 19 (2) Subtract (2) from (1)
4y = -8 divide both sides by 4
y = -2 (the y-coordinate of the solution point)
Replace -2 for y at one of the given equations, let's say at (2).
-5x +3(-2) = 19
-5x - 6 = 19 add 6 to both sides
-5x = 25 divide both sides by -5
x = -5 (the x-coordinate of the solution point)
Thus, the solution point is (-2, -5).
how many solutions does the equation have? 4x+1=5+2(2-4) a. one solution b. infinite solutions c. no solution
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
x2-5x = 24 x2-5x-24 = 0 (x-8)(x+3) = 0 x = 8 or x -3
If you mean 5x = 140 then the value of x is 140/5 = 28
5x-3 = 37 5x = 37+3 5x = 40 x = 8
It is simply 5x + 10. Since it is an expression, there can be no solution.
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
5x = 15 so x = 15/5 = 3
That all depends.Is it:ln (2x+9) = ln (5x)If it is, the solution can be found by solving 2x+9 = 5x, in which case the answer is x = 3.
graph the inequality 5x+2y<4
y + 5x = 6 if x = {-1, 0, 1}
It is an algebraic expression that can be simplified to: 11x+5
There is a formula for the "difference of squares." In this case, the answer is (5x + 3)(5x - 3)
yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5
The given expression has no solution but it can be simplified to: 5x-1045
No solution.
