5x + 2 -x = -4x
4x +2 = -4x
2 = -4x -4x
2 = -8x
x = - 1/4
hope this helps
Answer:
x = 1
y = 4
Step-by-step explanation:
9x + 5y = 29 eqn 1
3x + y = 7 eqn 2
Using the method of substitution,
"substituting y"
multiplying through eqn 2 by -5
-15x - 5y = -35 eqn 2
9x + 5y =29 eqn 1
adding eqn 1 and eqn 2
-6x = -6
x = 1
3x + y = 7
3 (1) + y = 7
3 + y = 7
y = 7 - 3
y = 4
Square, perpendicular and of equal length must mean a square by definition
