-9r plus 10r can be written as ( -9r + 10r) and the answer is r.
5t-26 = 18t -26 = 18t -5t -26 = 13t t = -2
18t + 4x -47t + 50x = -29t + 54x
i have a Johnson MQ-10R it is a 1964 model
the answer is -10r
-11r
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
They're the same.
-9r = 20 + rsubtract r from both sides-10r = 20divide both sides by -10r = -2
3(5 + 6t)
6t
it cant be reduced
