After 5 years they will not be as tall each other.Ben will be 4 feet and 7.5
and Johnny will be 3 feet and 10.8.
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.
First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3
Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42
Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3
Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8
So, we can conclude that the correct answer is B. (-8,3)
Answer:
No solutions
Step-by-step explanation:
4(x + 3) - 4 = 8x + 10 - 4x
4x + 12 - 4 = 8x + 10 - 4x
4x + 8 = 4x + 10
4x = 4x + 2
0 ≠ 2
Best of Luck!
