2x plus 3y equal 40 -2x plus 2y equal 20?
2x+3y=40-2x+2y=20Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.3y=-2xDivide each term in the equation by 3.(3y)/(3)=-(2x)/(3)Simplify the left-hand side of the equation by canceling the common terms.y=-(2x)/(3)if you were solving for x It would be x=-(3y)/2
What does y equal in this equation 8x plus 6y equals 16 4x-2y equals 8?
x = 2, and y = 0. Here's one way to solve:Multiply the second equation (both sides) by 3, then add the two equations:8x + 6y = 1612x - 6y = 24----------20x = 40 ----> x = 2, then substitute x=2 into one of the original equations:8*2 + 6y = 16 --> 6y = 0, and y=0. Check with the other equation: 4*2 - 2y = 8 ---> -2y = 0, and y = 0.
How do you solve 8-3x equals 128?
8-3x = 128 -3x = 128-8 -3x = 120 x = -40
What is the answer to 5x plus 10 equals 40?
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
What is 5x plus 32 plus 7x plus 8 equals 180?
5x+32+7x+8=180. By the laws of commutativity we can thus say that 12x+40=180. Subtracting 40 we get 12x=140. Divide by 12 and you get x=(do it yourself) This has nothing to do with calculus by the way.
Solve by the method of elimination 2x plus 3y equals 40 3x plus 2y equals 20?
y=16 x= -4
What is the solution for 2y-5 equals 11y plus 40?
2y-5=11y+40 Subtract 2y from both sides -5=9y+40 Subtract 40 from both sides. -45=9y Divide by 9. -5=y
2x plus 3y equals 40 and -2x plus 2y equals 20?
Add the two equations you get 5y = 60 so y = 12 and x = 2
20h-40 equals 8h plus 152?
How do you solve this equation 20h-40=8h+152 ?
Solve this equation -9-6 plus 12h plus 40 equals 22?
h= -4
Can you solve the simultaneous equation 4x plus 3y equals 4 and x-2y equals -10 with steps?
4x + 3y = 4 x - 2y = -10, so add 2y to both sides gives x=2y-10, replace this into first equation gives: 4(2y-10) + 3y = 4, expand that gives 8y-40+3y=4, add 40 to both sides, this gives: 8y + 3y =44, or 11y = 44 giving you y=4. You have solved for y, now solve for x: 4x + 3y = 4, gives 4x +12 = 4, or 4x=-8 giving x=-2. So x=-2 and y=4. QED.
What is the answer of 6y-2y equals 40?
6y-2y=40 6-2=40/y 4=40/y y=10 6(10)-2(10)=40
Solve this equation -9h - 6 plus 12h plus 40 equals 22?
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
Solve the following 32 divided by 4 plus 4 x 8 equals?
The final answer is 40.
What is the ordered pair of the solution -4x plus 8y equals 40 and -2x-2y equals 2?
[x = -4, y = 3]. There is more than 1 way to solve. Here's one:multiply second equation by 4: -8x - 8y = 8add to first equation {eliminating y}: -12x = 48divide this by -12: x = -4.Now substitute x = -4 into either of the original equations:-2(-4) - 2y = 28 - 2y = 2 ---> -2y = -6 ---> y = 3.Check in the other equation: -4(-4) + 8(3) = 16 + 24 = 40 [checks out]
What is 40 plus 40 plus 40 equals?
120
Solve this equation negative9h-6 plus 12h plus 40 equals 22?
-9h-6+12h+40=22 -9h+12h=22-40+6 3h=-12 h=-4
