Answer:
6.8+3.4=10.2
Step-by-step explanation:
Answer : x=-2,y=4.
The second equation is multiplied by 5 and give it equation (3) and then subtract the first and third equations .You’ll first get the value ‘y’ and then substitute the value of ‘y’ in the first equation.Finally you’ll get the value of ‘x’.
Answer:
Jake is 9, and Jake's dad is 43.
Step-by-step explanation:
Ok, let's start off by putting a variable for Jack's age, A.
We know that Jack's father is 2 less than 5 times, so we can write his as 5x -2.
Now let's make an equation:
52 = x + 5x - 2
We need to isolate the x-values so we need to add 2 on both sides:
54= x + 5x
No we need to add the like terms:
54 = 6x
Finally, we just divide by 6 on each side.
Now we know X = 9 but we're not done yet :)
So because Jake's dad is almost 5 times as much, we first multiply Jack's age by 5. We get 45 but we need to subtract 2 which leaves us with 43.
