How do you solve -2a plus 5 plus 3a equals 15-21?
depends what 'a' =
How do you solve -2a plus 5 equals 1?
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
How do you solve b equals 2a plus 11 and a plus b equals 5 by substitution?
b = 2a + 11a + b = 5 which is b = 5 - atherefore2a + 11 = 5 - a (which is b = b)2a + a = - 11 + 53a = - 6a = - 2looking at first equation substitute - 2 for a:b = 2a + 11b = 2*(- 2) + 11b = - 4 +11b = 7to check:a + b = 5- 2 + 7 = 5
A plus a plus a-2a equals?
a + a + a - 2a = 3a - 2a = a

How do you Solve this system of equations using the addition method 6a - 5b equals 9 2a plus 5b equals 23?
the answer
2a plus 3 equals 11?
yes, if a=42a+3=112x4=88+3=11
What is the solution to a equals 3a plus 4?
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
If b equals a plus 40 and 2a plus 2b equals 160. solve for a and b?
2a + 2b = 160 But b = a + 40 so 2a + 2(a + 40) = 160 ie 2a + 2a + 80 = 160 or 4a = 80 ie a = 20 Then b = a + 40 gives b = 20 + 40 = 60 Solution: a = 20, b = 60
