Step-by-step explanation:
first distribute the 5.
10x-40=90
then get rid of the 4o and add it to 90
10x=130
then divide by 10 to get x alone
x= 13
Answer:
x = 13
Step-by-step explanation:
5(2x - 8) = 90 Divide by 5 on both sides
2x - 8 = 18 Add 8 to both sides
+ 8 + 8
2x = 26 Divide by 2 on both sides
x = 13
