5+x=42.
42-5=37
x=37
42 72
x = 47/42
2x plus 6y equals 32 32 divided by 6= 5 R2 5+2= 7x6= 42-5=37-2=35 so X=5
-55
The answer is 7
15
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
x = 15
5x + 43 = 42 5x = -1 x = -1/5 Check it. -2 + 43 + 1 = 42 42 = 42 Check.
x = 5
If its x+4x+5 then: 5x+5
