It is a straight line equation and its solution is worked out as follows:- Points: (2, -5) and (4, 3) Slope: (-5-3)/(2-4) = 4 Equation: y--5 = 4(x-2) => y = 4x-8-5 => y = 4x-13 Equation: y-3 = 4(x-4) => y = 4x-16+3 => y = 4x-13 So in slope-intercept form: y = 4x-13 whereas 4 is the slope and -13 is the y intercept
4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.

It is a straight line equation and its solution is worked out as follows:- Points: (2, -5) and (4, 3) Slope: (-5-3)/(2-4) = 4 Equation: y--5 = 4(x-2) => y = 4x-8-5 => y = 4x-13 Equation: y-3 = 4(x-4) => y = 4x-16+3 => y = 4x-13 So in slope-intercept form: y = 4x-13 whereas 4 is the slope and -13 is the y intercept
We start with 4x + 8 = 5x -5. Subtract 4x from both sides of the equation, which gives us 8 = x - 5. Add 5 to both sides of the equation, this gives us 13 = x. Problem solved.
Parallel, the slope of the second equation is 4
5 it is 5 because 13 + 7 = 20 20 divided by 4 is 5 to find out the answer, work through the equation backwards and use the opposite operations.
Let the unknown number be x: 4x-7 = 13 Moving -7 to the other side of the equation changes it to +7: 4x = 13+7 4x = 20 Divide both sides of the equation by 4 to find the value of x: x = 5
4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
4x - 5 + 1 = 8Add +5 - 1 to both sides of the equation.4x -5 +1 + 5 - 1 = 8 + 5 -14x = 12Divide both sides of the equation by 4.4x/4 = 12/4x = 12/4 = 3
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
8x+5=4x+13 4x=8 x=2 Therefore, your answer is 2.
I think this might read "4x+5 = 4x-1". Subtracting 4x from both sides cannot upset the equality, and then you have +5 = -1, which is nonsense. One moral of this is "make sure your equation makes sense, and actually includes an = sign."
