What is the answer to 1-5x plus 7x?
1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
What is the solution to 7x take away 1 equals 2x plus 5?
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
How do you solve the equation 5x plus 34 -2(1-7x)?
Unfortunately, the browser used for posting questions is hopelessly inadequate for mathematics: it strips away most symbols. All that we can see of the so called equation is "5x plus 34 -2(1-7x)?". From that it is not at all clear where the missing symbols might be.Assuming the equation is 5x plus 34 = -2(1-7x),Expand the brackets: 5x + 34 = -2 + 14xAdd 2 to both sides: 5x + 36 = 14xSubtract 5x from both sides: 36 = 9xDivide both sides by 9: 4 = x.
Which expression is equivalent to 5x(x 2) -3(x-1)?
If you mean: 5x(x+2)-3(x-1) then it is 5x^2 +10x-3x+3 or as 5x^2 +7x+3
Solve for x 5x over 10 2 a 1 b4 c 5 d 20?
It's impossible to solve x 5x over 10 2, as the equation doesn't make sense the way it's structured.
How do you solve 7x minus 1 equals 9 plus 5x?
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
Solve 2x plus 5x-1 equals 9x?
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
7x-3 equals 5x plus 1?
7x -3 = 5x + 1 solve for xadd three to both sides7x = 5x + 4subtract 5x from both sides2x = 4divide both sides by 2x = 2
What is the answer to 1-5x plus 7x?
1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
What is -5x-(7x plus 2)?
-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
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)
How do you solve this factor problem of x3-6x2 plus 7x-2?
(x - 1)(x^2 - 5x + 2)
What is the trinomial 5x squared plus 7x plus 2?
5x2+ 7x + 2 = (x + 1)(5x + 2).
Seven x +three x-x-five x?
7x + 3x - x - 5x simplifies to 6x - x, or 5x. To solve this equation, you can use the distributive property, which states that a(b + c) = ab + ac. In this case, 7x + 3x is the same as 7x times 1 + 3x times 1, or 7x + 3x. x - x is equal to 0, since anything minus itself is always equal to 0. Then, 5x is the same as 5 times x, or 5x.
5x squared plus 7x equals 12?
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
5x-15x plus 10?
5x-15x+10 = 10-10x when simplified Assuming a request to solve the equation: 5x -15x + 10 = 0 5x - 15x + 10 = 0 5x - 15x = -10 or (multiplying everything by -1 gives you -5x + 15x = 10) so 15x - 5x = 10 10x = 10 x =1
What would the answer be to 5x plus 9 minus 7x plus 6 equals x plus 18?
Do you mean: 5x + 9 - 7x + 6 = x - 18 If so, you can solve this question at this manner: -2x + 15 = x - 18 3x = -3 x = -1
