1+x=dd+x so dd=1 so d=1
1+x=89b+x so 89b=1 so b=1/89
bc+x=1+x so bc=1 so c=1/(1/89) = 89
so cd=89 (and x=88)
Yes because if 1+0=1 than 0 plus b equals b
That factors to (a + 1)(a + b) a = -1, -b b = -a
The value of b is 44.5 * * * * * Missed the 2! b + 2b - 1 = 88 Combining like terms: 3b - 1 = 88 Add 1 to both sides: 3b = 89 Divide both sides by 3: b = 89/3 = 292/3
The commutative property of addition. a + b = b + a
z remains undefined.

The commutative property of addition. a + b = b + a
a+b+c+d+e = 30 (i) c+e = 14 (ii) d+b = 1 (iii) a = 2b-1 (iv) a+c = 10 (v) By (i)-(ii)-(iii): a = 15 then, by (iv): b = 8 and by (v): c = -5 Also, b = 8 so by (iii): d = -7 and then by (i), e = 19
It is called the commutative property, a + b = b + a
A = 1, B = 9
a= 2, b = 3 (or vice-versa)
the y-1 is a minus .
the answer is a
z remains undefined.
If ba = 2a + b , then find 23 + 32 +1
