I'm guessing at what you want. I think you want to know the number, but you could also just want the equation.
Step One
Start with "the sum of a number and - 3." That looks like this.
x + - 3 = x - 3
Step Two
"Is multiplied by - 5"
- 5 (x - 3)
Step Three
"... the result is 35"
-5(x - 3) = 35
Solve
You can remove the brackets or divide by - 5
-5x - 15 = 35 Add 15 to both sides
- 5x = 35 + 15
-5x = 50 Divide by - 5
x = 50/-5
x = - 10 <<<< Answer
Answer:
Their combined height is 108 inches
Step-by-step explanation:
1 ft = 12 inches
12 * 4 = 48 inches
48 + 6 = 54 inches
54 * 2 = 108 inches
Answer:
-7/3 =x
Step-by-step explanation:
5x-15 = 8x-8
Subtract 5x from each side
5x-5x-15 = 8x-5x-8
-15 = 3x-8
Add 8 to each side
-15+8 = 3x-8+8
-7 = 3x
Divide each side 3
-7/3 = 3x/3
-7/3 =x
