2(3x - 5) +4(5x+1) - (x+2) expand and multiply
Here +2 is within the first bracket. When we are multiplying it by -1 and removing the bracket, we are not only multiplying the numbers but also their signs. As per the rule of signs, a positive(+) sign multiplied by a negative(-) sign yields a negative(-) sign or two unlike signs make a negative sign. So, in the given problem +2 becomes -2.
Multiply the terms using distributive property and remove the brackets:
Now arrange the like terms:
Hence, the required answer is 25x-8.
