Solve for x. Show all work. 2/3 (x+7) =10

8

Step-by-step explanation: 10 divided by 2/3 is 15 so we need to in the parentheses create 15 and 15 - 7 is 8 so the value of x is 8 hope it helps

answer is 8

Step-by-step explanation:

2/3(x+7)=10

2x/3+14/3=10

2x/3=10-14/3==>30-14/3

2x/3=16/3

x=16/3*3/2

x=8

reduce the friction between its moving parts

step-by-step explanation:
