Not illustrated. 1830 Excerpt: ... SIMPLE EQUATIONS. A person has a certain number (x) of apples; if (x + 3) be multiplied together three times, and this product be divided by (x, + 6x + 9) the quotient is 10. What is the value of A person thinks of a number, he multiplies it by 7, he then increases this product by 3; then he divides this number by 2; lastly, he subtracts 4, and has 15 remaining. Find the number he thought of. Let x = the number he thought of.! 3-4 = 15 multiply both sides by 2. 7x + 3--8=30 7=30+8--3=35.-. x=Y = 5. If I divide a certain number by 25, and subtract 3 from the quotient, and then add 51, and afterwards subtract 40, I shall have 12 remaining. Find the first number. Let x = number sought..-.- -3+51-40 = 12 25....=55-51=4 25 Then multiplying both sides by 25 =100. How much money have I in my pocket when the 4th and 5th parts together amount to 11s.: 3d.? Let 20# denote the pence.... the 4th part is 5x the 5th part is ax... 9#=135 pence.-. #==1 = 15;.-. 20x = 300d. = l:5:0d. Divide the number 46 into two such parts, that when the one is divided by 7, and the other by 3, the quotients may amount to 10. Find the parts. Let x = one part... 46--x = the other....u=2.+i-l- m A person thinks of a number (x), he multiplies this number by itself, from this last number he subtracts a given number (a2); he then divides the remainder by x--a, and the quotient is = b; find x. x3--a2-=-(x--a) = b ut x3-- ?- -x--a) = x + a.. x + a = b.. x = b--a. Divide the number 90 into four such parts, that if the first be increased by 2, the second diminished by two, the third multiplied by 2, and the fourth divided by 2, the result in each case will be the same. Let x = the third part, .. 2x = half the fourth, .. &...
