The equation x+9/7 =15 can be solved by performing two operations on both sides. State the operations in order of use. There may be more than one correct answer. A. Multiply both sides by 7 first, then subtract 9 from both sides
B. Subtract 9 from both sides first, then multiply both sides by 7
C. Divide both sides by 7 first, then subtract 9 from both sides
D. Subtract 9 from both sides first, then divide both sides by 7
E. Multiply both sides by 7 first, then divide both sides by 9
F. None of the above

(b) Give the solution of the equation x+9/7 =15.
X= ?

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.

40-24 to 4: 740+24=class4=boys 7=gals =4: 7

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
