2x plus 7 plus 2x equals 23?
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
What is the answer to 2x plus 5 equals equals 13?
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
What is 2x-3 equals 13?
2X - 3 = 13 add 3 to each side 2X = 16 divide both sides by 2 X = 8 check 2(8) - 3 = 13 13 = 13 checks
What is the value of 2 x plus 3 equals 23?
2x+3=23 minus 3 from both sides 2x=23-3 so we get 2x=20 divide both sides by 2 to get the value of x x=10
What is 2x -9 equals 7?
23
What two step equstions equal 13?
2x - 1 = 25 or 2x - 3 = 23 or many others
2x plus 7 plus 2x equals 23?
2x + 7 + 2x = 23 4x + 7 = 23 4x = 16 x = 16/4 x = 4
What is the Integral of 23x e2x dx?
This browser is pathetic for mathematical answers but here's the best that I can do:Let u = 23x therefore du/dx = 23let dv/dx = e^(2x) therefore v = 1/2*e^(2x)then, integrating by parts,I = I(u*dv/dx) dx = u*v - I(du/dx*v) dx= 23x*(1/2)*e^(2x) - I(23*(1/2)*e^(2x) dx= 23/2*xe^(2x) - 23/2*I(e^(2x)) dx= 23/2*xe^(2x) - 23/2*(1/2)*e^(2x)= 23/2*xe^(2x) - 23/4*e^(2x)or 23/4*e^(2x)*(2x - 1)
What is 2x plus 1 equals 13?
2x + 1 = 13; 2x = 12; x = 6
What is 2x-13 equals 5 This is an equation please help?
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
What is 3x plus 5 equals 2x plus 13?
3x+5 = 2x+13 3x-2x = 13-5 x = 8
What is the answer to 2x plus 5 equals equals 13?
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
How do you solve for y if -2x plus 13y equals 11?
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
What is 9 minus 2x equals 35?
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
What is the expression of 26x-13 using greatest common factor?
13(2x - 1)
How do you solve x-29 equals 13 plus 2x?
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
What is 4 plus 2x minus-2x plus 1 equals 13 plus 6?
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
