h+1.5=8.4
subtract 1.5 from both sides
h=6.9
-0.5
+6
5x+y=-7 3x+y=15 8=D
y=±√15
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
The answer to the equation 80 times 3 Y plus 2 Y plus 4 plus 1 equals -15. This is considered to be a math problem.
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
x2+x-15 = 0 Using the quadratic equation formula: x = 3.405124838 or x = -4.405124838
