To solve the equation "blank plus 9 times 3 equals 45," we first need to simplify the expression on the right side. 9 times 3 equals 27. Therefore, the equation can be rewritten as "blank plus 27 equals 45." To isolate the variable "blank," we subtract 27 from both sides of the equation. The solution is blank equals 18.
It is an equation and the value of x is -3

6x-14x+16=27+11 answer: 4
Improved Answer:-If: 20x+27 = 143Then: x = 5.8
27
Presumably this is a simultaneous equation in the form of: -4x+3y = 27 -2x+y = -1 Multiply all terms of the bottom equation by 2: -4x+3y = 27 -4x+2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a + Meaning that -4x - -4x = 0 and 27 - -2 = 29: So y will = 29 Substitute the value of y into the original equations to find the value of x Therefore: x = 15 and y = 29
The value of x is -4
2 squared is 4 3 cubed is 27 27 plus 4 is 31
It has one double solution.
x = 5 or x = 6
To solve for b in the equation b + 15 = 27, you need to isolate b on one side of the equation. To do this, you can subtract 15 from both sides of the equation. This gives you b = 27 - 15, which simplifies to b = 12. Therefore, b equals 12 in the given equation.
