What is the equation of 2x 1 equals 7?
im assuming your equation is 2x + 1 = 7 in this case you need to find what x equals 2x + 1 = 7 2x + 1 - 1 = 7-1 2x = 6 x = 3 put it back into the equation to check if your answer is correct 2(3) + 1 = 7 6 + 1 = 7 7 = 7 Correct! if your equation is 2x - 1 = 7 x = 4 check it 2(4) - 1 = 7 8 - 1 = 7 7 = 7 Correct! if your equation is 2x1 = 7 x = 7/2 check it 2(7/2)1 = 7 2(7/2) = 7 2 * 7 / 2 = 7 14/2 = 7 7 = 7 Correct! hope i got your equation right. if not you can message me on my message board to get more help.
What is the equation of the circle with a radius of 7 whose center is in the 1st quadrant and touches both the x and y axes?
Equation of the circle: (x-7)^2 +(y-7)^2 = 49
What is the equation of the circle with center 2 9 and radius 7?
depends on the equation.
How do you solve x - 2 5 and 7 equal 2 and 3?
x - 2 5/7 = 2/3 x - 19/7 = 2/3 x = 2/3 - 19/7 = 14/21 - 57-21 = -43/7 = -6 and 1/7
How do you solve equation x over 7 equals 2?
x/7 = 2 Multiply both sides by '7' 7x/7 = 7 x 2 = 14 On LHS cancel down '7' Hence x = 14
