Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
Step-by-step explanation:
Hey there!!
According to the question,
One number is 7.
Let another no. be x.
So, the condition is 6(x+7)= 30
Now,
6(x+7) = 30
6x +42 = 30
6x = 30-42

Therefore the no. is -2.
Check,
6(-2+7)= -12 + 42 = 30 { they gets subtracted but sign remains (+) only }.
