8x = 2x + 15 6x = 15 x = 15/6 = 2.5

8 , and 7. x+y=15 >> x=-y+15 x*y=56 >> y*(-y+15)=56 , then solve for y , put y back into either equation for x.
I assume that the question means 4x-7=2x+5. In that case, the answer x would equal 6.
2x+5x=35 what is x? x= 5 substitution ... 2x5= 10 5x5= 25 10+25= 35
No 2x5 does not =15. 2x5=10 ya big dummy
First, remember the order of operations. 2x5 comes first. 2x5=10, which makes 11-10 which makes 1.
A factor tree of 75,000 is 75,000 75 x 1000 (3 x 25) x (10 x 100) (3 x (5x5)) x ((2x5) x (10x10)) (3 x (5x5)) x ((2x5) x ((2x5)x(2x5))) So, the prime factorization is 2 x 2 x 2 x 3 x 5 x 5 x 5 x 5 x 5 = 23 x 3 x 55
they are telling u that X=5, so plug in a 5 anywhere there is an X, so now is 52 x 2x5= 5x5=25 , so now is: 25x(2x5), 2x5=10, so now is 25x10=250 ,so the answer is : x2x (2x) = 52x(2x)=52x(2x5)=25x2x5=250
There is not enough information to solve for x. x+5x+15 must equal something (is it 0?) in order to solve for x.
(2x5) x (55x56) ÷ 6 = 10 x 55 x 56/6 = 10 x 55 x 28/3 = 15400/3 = 5133.3333 It is the required answer.

x=15
Let x represent the unknown nimber. Set up the equation and solve (15% is the same as .15) .15 * x = 18 (next divide both sides by .15 to solve for x) x = 120 15% of 120 = 18
6n² example if n=5 (2x5) x (3x5) = 10 x 15 = 150 6 x 5² = 6 x 25 = 150
3 x 5 = 15
x - 15 = - 8 add 15 to both sides: x -15 + 15 = -8 + 15 simplify both sides: x = 7
