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 plus 35?
you can't solve that unless you know what the variable, expressed by x, is. if you have a whole equation, something like 5x+35=7x+6, then we could figure out what x is and solve your original problem.
Five times a number is 49 greater than the product of 2 and the opposite of the number what is the number?
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
How do you do the problem 65 equals 2x-7x?
65 = 2x - 7x 65 = -5x 65/-5 = -5x/-5 -13 = x
7x-3 plus 5x plus 15 180?
If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
How do you solve 7x equals 2x-4?
7x=2x-4 5x=-4 x=-4/5
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
How do i solve x x-2 equals 7x?
assuming the gap before x-2 is a +, then x+x-2=7x, so 2x-2=7x, so 5x=-2, so x=-.4
Solve for x. 129+(7x-46)+(9x-11)+94+(5x+17)?

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.
7x equals 5 plus 5x?
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
How do you solve this factor problem of x3-6x2 plus 7x-2?
(x - 1)(x^2 - 5x + 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.
Solve 2x plus 5x-1 equals 9x?
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
How do you solve 5x-3 equals 11 plus 12x the solution is x equals?
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
What is 5x plus 35?
you can't solve that unless you know what the variable, expressed by x, is. if you have a whole equation, something like 5x+35=7x+6, then we could figure out what x is and solve your original problem.
5x plus 17 equals 7x-123?
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
