What is 5x plus 3 equals 48?
If you have 5x+3=48takeaway 3 from both sides which leaves you with5x=45 then divide both sides by 5 which isx=9
What is the equation of the line that passes through (-3,5) and (0,-4)?
The vertical line that passes through the point (0, 4) is the Y-axis. Its equation isX = 0
What number is 12 percent of 225?
Follow these steps:Step1* 12(225) = x•100Step2* Now multiply 12x225=2700 = 2700/100 (cross out the 2 zeros from top to bottom.) now were left to 27/1Step3* Then multiply x times 100 = 100x/100Step 4* Forget about the 100x/100Step5* The multiply 27x1 = 27The answer isx=27
What number gives you the same result when you subtract or divide by 8?
The number 64/7 ( equal to 9 1/7 ).The equation isx - 8 = x/88 (x - 8) = x8x - 64 = x7x -64 = 07x = 64x = 64/7Checklng,64/7 - 8 = 64/7 - 56/7 = 8/764/7 divided by 8 = 8/7
Is there simultaneous equation which cant be solved?
By definition, there cannot be a simultaneous equation that cannot be solved, there must be a set of simultaneous equations. It is important to realise that simultaneous equations need not be linear.It is simple to devise a pair of linear equations that are inconsistent:x + y = 1 and x + y = 2There is no solution. Graphically, the two lines are parallel.Another possibility isx + y = 1 and 2x + 2y = 2In this case there are an infinite number of solutions. Graphically, the two lines are coincidet, so that every point on the common line is a solution. There is, therefore, no unique solution.Yet another situation can arise when the domain of the equations is restricted.For example,x2 + y2 = -1 where x and y are real along with any other equation in x and y.
