6r-r + 8(15-r)+23-6 is it equivalent to 3r+137
natita [175]

Answer:

No, it's not equivalent

Step-by-step explanation:

Try and solve the one with the bracket first. Expand 8(15-r) : 8x15 and 8x-r = 120 - 8r

Therefore, the equation can now be written as:

6r-r + 120-8r + 23-6

Rearrange the like terms together and solve the equation:

6r-r-8r + 120+23-6 = -3r + 137
