Answer:
u=95
Step-by-step explanation:
To solve this problem we need to isolate 'u' variable using properties of equation.
Lets multiply by -9 the whole equation
u - -23=-8*9
Remember keys features of algebra:
- * - = +
- * += -
+ * - = -
+ * + =+
So, our equations becomes>
u+23=-72
Lets now subtract 23 to both sides
u-23=-72-23
We have u=95
