7x+1 = (1/3)
2x + 2y = 28
Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)
Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)
I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.
Answer:
The man is 84
Step-by-step explanation:
84 x 2 is 168,
200-168=32
Answer:
see explanation
Step-by-step explanation:
Consider
x² = 64 ( take the square root of both sides )
x = 8 , x = - 8 ← are the critical points
Then for x² > 64
x < - 8 or x > 8
