find the value of y when x = 8
4 answers
Aren't you missing something in this problem? As you state it, it's not solvable.
Sorry, solve 3x+4y=8 for y and then using your answer find the corresponding value of y when x=8
3x+4y=8
3 * 8 + 4y = 8
24 + 4y = 8
4y = -16
y = -4
Proof:
24 - 16 = 8
3 * 8 + 4y = 8
24 + 4y = 8
4y = -16
y = -4
Proof:
24 - 16 = 8
3x+4y=8
3*8+4y=8
24+4y=8
4y= -16
y=-4
Proof 24-16=8
3*8+4y=8
24+4y=8
4y= -16
y=-4
Proof 24-16=8
