4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
-2x plus 3y equals 1
It is a straight line equation with a slope of 14 and a y intercept of -5
y = 2x + 1 IS a linear equation!
First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
In the straight line equation of y = 2x+14 the slope or gadient is 2 and the y intercept is 14
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
-2x plus 3y equals 1
It is a straight line equation with a slope of 14 and a y intercept of -5
If -2x +14 = 0, -2x = -14, or x = 7.
y = 2x + 1 IS a linear equation!
2x + 14 = 0Subtract 14 from each side of the equation: 2x = -14Divide both sides of the equation by 2: x = -7You can also obtain solutions to equations by visting wolframalpha.com. Enter solve 2x+14=0, for example. You can click on the 'step-by-step' button to see how the equation was solved.
First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7
2x-7y=14 2x-14=7y from this equation the slope is 2/7
balance the equation 3x-x=20-6 3x-x=2x 20-6=14 2x=14 x=7
There is only one equation, so it's not a system of equations.
