Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ← distribute the parenthesis by - 2
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
Answer:
3/4
Step-by-step explanation:
2/3a-1/6=1/3
2/3a=1/3+1/6
2/3a=3/6
2/3a=1/2
a=1/2X3/2
a=3/4
Step-by-step explanation:
2- 7x + 34 - 6-(766)
2-7x + 34 - 6 - 766
2 - 7x - 738
-7x - 736
-(7x + 736
452 because you will multiply 80 by 6 and get 480 and subtract 28 from that!
Let x = the unknown number to get x = 6
