What is the value of y in this equeation 3y equals 19 plus 5?
y = 8
What does 3y equals 12 equals what does 2y equal?
If 3y = 12, 2y = 8
What is the answer to 5x 8 equals 23?
if it is 5x + 8 = 23 then the answer is 3. if it is 5x - 8 = 23 then the answer is 31/5.
What is the answer to 3y - 7 equals 8?
y=5
What is the value of y in this equation 3y 19 plus 5?
If you mean: 3y = 19+5 then the value of y is 8
When x equals 8 what is the value of 5x?
When x equals 8, the value of 5x would be 5 times 8, which is 40.
How do you solve the linear system negative 5x plus 3y equals 51 and y equals 10x minus 8 with substitutions?
5x+3y = 51 y = 10x-8 Substituting the bottom equation into the top equation: 5x+3(10x-8) = 51 5x+30x-24 = 51 5x+30x = 51+24 35x = 75 Divide both sides by 35 to find the value of x: x = 75/35 = 15/7 in its lowest terms. Substitute the value of x into the original equations to find the value of y: So: x = 15/7 and y = 94/7
What is the absolue value of 5x plus 8 equals 6?
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
How do you solve for 8x-y equals 4 and 5x plus 3y equals 17?
A system? Try elimination 3(8X - Y = 4) 5X + 3Y = 17 24X - 3Y = 12 5X + 3Y = 17 -------------------------+ 29X = 29 X = 1 -----------find Y 8(1) - Y = 4 - Y = - 4 Y = - 1 -----------check By inspection one can see this is inconsitent
What is the slope of a line perpendicular to the line whose euation is 5x plus 3y equals 8?
-5/3
What is 5x-3y equals 8?
Am I solving for y or for x? x=1.6+0.6y y=-2.66666666...-1.666666666...
What is the slope of the line given by the equation 8 equals 3y-5x?
First rewrite the equation in the "standard" form: 3y = 5x + 8 so that y = 5/3*x + 8/3 Then the slope is the coefficient of x, ie 5/3 or 1.66...
How do you solve the simultaneous equations of x over 3 minus y over 4 equals 0 and x over 2 plus 3y over 10 equals 27 over 5 by the elimination method?
x/3-y/4 = 0 => multiply all terms by 12 => 4x-3y = 0 x/2+3y/10 = 27/5 => multiply all terms by 10 => 5x+3y = 54 4x-3y = 0 5x+3y = 54 Add both equations together which will eliminate 3y: 9x = 54 Divide both sides by 9: x = 6 Substituting the value of x into 5x+3y = 54 and 4x-3y = 0 gives y a value of 8. Therefore: x = 6 and y = 8
What is the value of the expression 5x plus 12y if x equals 8 and y equals 7?
5x=4012y=84124
What is the answer for 13 equals 5x-8?
The value of x is 4.2
What is the answer to -3x-3y equals 3 and y equals 5x-17 using substitution?
It is set for substitution. -3X - 3Y = 3 Y = 5X - 17 ( you have Y given to you, so substitute ) -3X -3(5X - 17) = 3 distribute -3X - 15X + 51 = 3 -18X + 51 = 3 -18X = -48 X = -8/3 Now substitute back into first equation for Y -3(-8/3) - 3Y = 3 8 - 3Y = 3 -3Y = -5 Y = 5/3 You preform the check ( it checks in first equation )
What is the value of y in 3y equals 19 plus 5?
y = 8
