15 + 3x + 3 = 3(5 + x + 1);

3x + 18 = 3x + 18

The equation is TRUE.

3x + 18 = 3x + 18

The equation is TRUE.

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

3(5+x+1)

=3*5+3*x+3*1

=15+3x+3.

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.

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)
