How do you solve 3b plus 2a equals 2 and -2 plus a equals 8?
3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.

-2b plus 7-3b equals 2?
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
What is 2a plus 3b equals 6ab?
With the assumption your asking what a or b are in terms of each other. a=3b/(6b-2) b=2a/(6a-2)
How do you solve 3b plus 2a equals 2 and -2 plus a equals 8?
3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.

How do you factor ab plus 2a plus 3b plus 6?
(a + 3)( b + 2)
Could you work out these simultaneous equations 2a plus 3b equals 13 and a plus 2b equals 8 and show me the working out please because I'm really stuck?
I think you have 2a + 3b = 13 2b = 8 If so, the second equation gives, by dividing both sides by 2, b = 4 then plug in b = 4 in first equation 2a + 3(4) = 13 2a + 12 = 13 2a = 1 a = 1/2

How do you graph 2a plus 3b equals 6?
Assuming that the horizontal axis is for a and the vertical axis is for b,Cover up 2a so you get the equation 3b = 6 which gives b = 2.Mark the point (0, 2) on the coordinate plane.Cover up 3b so you get the equation 2a = 6 which gives a = 3.Mark the point (3, 0) on the coordinate plane.Join the two points and extend the line in both directions.Done!
What is the answer to 6a plus 2 equals 2a plus 10?
A=2
What would a be if 2a plus 12 equals 8?
2a+12=8 2a=-4 a=-2 So a is -2.
