7x equals 5 plus 5x?
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
How do you solve 5X plus y equals -12 7X -3y equals -30 by elimination method?
(1) 5x+y=-12 (2) 7x-3y=-30 From (1) one gets y = -12-5x Put into (2) 7x-3y = 7x -3 (-12-5x) = 7x + 36 +15 x = 22x +36=-30 22x = -30-36 = -66 so x = -3 and y=-12-5x = -12-5x-3= 3 The solution is (-3,3)
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.
What is 5x - 3y -7x plus 2y plus 3x?
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
What is 5x-8 plus 7x simplified to?
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
7x equals 5 plus 5x?
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5

7x plus 12 equals 5x plus 2?
x = -5
5x plus 32 equals 7x plus 8?
x=12
5x plus 17 equals 7x-123?
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
If madc equals 7x plus 3 and mdcb equals 5x plus 9 then mdab?

How do you do 24 equals 7x plus 5x?
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
If mbad equals 5x plus 8 and mbcd equals 7x-4 then mabc equals?
