depends what 'a' =

-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2

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 + a + a - 2a = 3a - 2a = a

2a+5a+9a = 16a

If: 2a+13 = 5a+1 Then: a = 4

Subtract 2a from each side: P - 2a = b ie b = P - 2a

a+a=1 2a=1 a=1/2

a + a + a - 2a = 3a - 2a = a

5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9

Solve the following equation for A : 2A/3 = 8 + 4A

the answer

yes, if a=42a+3=112x4=88+3=11

a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
