3a + 4b - 5 - 1a + 7b + 3 - 1b 2a + 10b - 5 + 3 2a + 10b - 2
It is -10b - 7.
The Answer to this question is 9 (2B+4) and (1B+3)
b = 6
4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3
3a + 4b - 5 - 1a + 7b + 3 - 1b 2a + 10b - 5 + 3 2a + 10b - 2
-5 + 10b = -3110b = -26b = -2.6
It is -10b - 7.
10b
The Answer to this question is 9 (2B+4) and (1B+3)
198b + 4
The given expression can be simplified to: 3b-a
b = 6
That depends what the value of a and b are.
The answer to 5 times 3 is 15. This is so because if you add 5 plus 5 plus 5 , or 3 plus 3 plus 3 plus 3 plus 3, your answer would be 15. :)
10b
4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3
