If you mean: -4a+5-2a-9 = 44 then 'a' works out as -8 Check: -(4*-8)+5-(2*-8)-9 = 44
X - 5 = 4add 5 to each sideX = 9======check in original equation(9) - 5 = 44 = 4------------checks
2a + 21 = 8a - 9Add 9 to each side:2a + 30 = 8aSubtract 2a from each side:30 = 6aDivide each side by 6:5 = a
Without an inequality sign it can't be considered to be an equation but it can be simplified to: 4-2a
2a-6a+9-4a+9
If you mean: -4a+5-2a-9 = 44 then 'a' works out as -8 Check: -(4*-8)+5-(2*-8)-9 = 44
2a - 1 = 9 Therefore, 2a = 10 a = 10/2 = 5 Therefore, a = 5.
44 - 9 + 6 + 5 + 4 + 32 + 5 = 87
The integers are -9, -7, -5, -3 (16 is 4 more than 12) The equation is: - (A + A+2) = -4 (A+6) +4 -2A - 2 = -4A - 24 +4 2A - 2 = -20 2A = -18 A = -9
2*9 - 5 = 18 - 5 = 13
Yes, 44 can be written as 2+3+4+5+6+7+8+9 = 44

2a + 21 = 8a - 9Add 9 to each side:2a + 30 = 8aSubtract 2a from each side:30 = 6aDivide each side by 6:5 = a
-4 + 10 + 6a - 2a + 3 9 + 4a
Your numbers are -2 and -7 and here's how you find them: a + b = -9 b = -9 - a b = (-9 - a) [We have now found the value of b in terms of a.] a - b = 5 a - (-9 -a) = 5 a +9 + a = 5 2a + 9 = 5 2a = -4 a = -2 [We have solved for a, and now we substitute that back in to solve for b.] a + b = -9 -2 + b = -9 b = -7 [And now we've solved for b, the second unknown, and solved our problem.]
5-4 = 1 8-5 = 3 = 1*3 17-8 = 9 = 3*3 44-17= 27 = 9*3 let the number be x difference between 44 and x = 27*3 = 81 x = 44 + 81 = 125
2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
