It is true that 15+3x+3=3(5+x+1).
3(5+x+1)
=3*5+3*x+3*1
=15+3x+3.

Simplify 1+4(3b+9)-b is as follows:
1+4(3b+9)-b
=1+4*3b+4*9-b
=1+12b+36-b
=12b-b+1+36
=11b+37.

solve: x-3/3+x-3/4=7/24
Weegy: x - 3/3 + x - 3/4 = 7/24 Simplify. x - 1 + x - 3/4 = 7/24 Move all terms with the variable x to the left and all other terms to the right, remembering to switch signs when we switch sides. x + x = 7/24 + 1 + 3/4 Simplify the left side. [ Find a common denominator on the right. 2x = 7/24 + 24/24 + 18/24 Add across the top on the right, now that we have a common denominator. 2x = 49/24 Divide both sides by 2. x = 49/48 This is not in your list of answers. Did you forget the brackets? Is this the original question? (x-3)/3 + (x-3)/4 = 7/24 Let's try that instead. First, we want to get rid of the fractions. Multiply each term by 24. 8(x-3) + 6(x-3) = 7 Expand and simplify. 8x - 24 + 6x - 18 = 7 Move all terms with the x to the left (already there) and all other terms to the right. 8x + 6x = 7 + 24 + 18 Simplify each side. 14x = 49 Divide by 14 and reduce. x = 49/14 = 7/2 = 3.5 7/2 is in your list of answers. ] (More)
