Answer:
about 4,400 times
Step-by-step explanation:
its simple
3x - 4y = 18
9x + 2y = 12
Solve for x in the first equation.
3x - 4y = 18
3x = 18 + 4y
x = (18 + 4y)/3
x= 6+4/3y
Put x as 6+4/3y in the second equation and solve for y.
9x + 2y = 12
9(6+4/3y)+2y =12
12y+54+2y=12
14y+54=12
14y=12-54
14y=-42
<h2>y = - 3</h2>
Put y as -3 in the first equation to solve for x.
3x - 4y = 18
3x - 4(-3) = 18
3x+12=18
3x=18-12
3x=6
<h2>x = 2</h2>
