Answer:
4
Step-by-step explanation:
We convert this word equation to a number equation, then work it out.
7+4x=23 Use 'x' for the number we want to find.
4x=16 Subtract 7 on both sides.
x=4 Divide both sides by 4
Answer:
The missing number equals -5/4.
Other ways of writing this include...
1. -1.25
2. -1 1/4
Step-by-step explanation:
The equation used to solve this problem is...
4 * (x + 7) = 23
x: the missing number
1. Divide both sides by 4.
4 * (x + 7) / 4 = 23 / 4
2. Simplify.
x + 7 = 23 / 4
3. Subtract 7 from both sides.
x + 7 - 7 = 23/4 - 7
4. Simplify.
x = -5/4
