Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0
What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
How can you convert 3x plus 4y equals 4 into slope-intercept form?
3x+4y = 4 4y = -3x+4 y = -3/4x+1 So the slope is -3/4 and the intercept is 1
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
The graph of 3x plus 4y-4 equals 0 crosses the line y equals -2 at what value of x?
3x + 4y - 4 = 0 y = -2 3x + 4(-2) - 4 = 0 3x - 8 - 4 = 0 3x = 12 x = 4 (4,-2)
What is 3x 4y-17?
3x+4y = 17 -3x -3x 4y = -3x+17 Divide each TERM by 4 y = -3x + 17 4 4
What is the slope of the line that is parallel to the line represented by the equation 3x - 4y equals 12?
Lines parallel to the line would have the same slope, which is 3/4. (0.75) 3x-4y = 12 3x-12 = 4y y = 3/4 x - 3 The y-intercept is -3 and the slope is 3/4.
Simplify 3x plus 2y plus 2 equals 4y plus 4?
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
Solve for x 3x - 2y equals 6?
x=4 x=4
What is a like term in math?
Two terms that have the same variables and you can combine them in addition. For example, 3x and 34x have the same variable, and when you add them, they combine to form 37x. 4y and 4 do not have the same variable and you cannot combine them in addition. For example, 4y + 4 equals 4y + 4; it cannot be simplified or combined.
Solve 6 minus 3x equals 4 minus 2x?
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
If P equals 2y-6xy-3x and Q equals 4-5y find 2P-3Q and simplify your answer?
2p = 4y - 12xy - 6x, 3q = 12 - 15y so 2p - 3q = 4y - 12xy - 6x - (12 - 15y) = 4y - 12xy - 6x - 12 + 15y = 19y -12xy - 6x - 12
-4y plus 11 equals -5?
11-4y=-5 -4y=-16 y=4
Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
How can you figure out the y-intercept is?
Since the y-intercept is the part of a graph that crosses the y-axis all you have to do isLet x = 0 and solve for y.Example: Find the y-intercept of 3x + 4y = 12let x =0 -> 3(0) + 4y = 124y = 12divide by 4 -> y = 3 so the y-intercept is the point (0,3)That is where the graph 3x+4y = 12 crosses the y-axis.
Solve this equation 4y plus 228 equals 352?
really strait forward, all you have to do is isolate y to one side of the equation 4y+228=352 4y = 352-228 y = (352-228)/4 y = 124/4 y = 31
What does x equal in 3x 4-11?
what does the equation equal? if it equals zero: 0= 3x(4-11) 0=3x(-7) 0=3x 0=x if the equation doesn't equal anything, it means it's just an expression meaning you can't solve for x, you can only reduce (and this equation is already reduced). if the equation equals y, you need another equation and use either substitution or elimination to solve for x.
