Best Answer

Yes, it can be solved for x = ? because there is one equation and one variable.

x2 - 9x = -20

x2 - 9x + 20 = 0

(x-4)(x-5) = 0

The factoring takes some practice. Now we set each parenthesis equal to zero, and we get two possible values for x: x = 4 and x = 5.

Q: Can you solve x2 minus 9x equals -20?

9x - 20 = 61 Add 20 to both sides: 9x = 81 Divide both sides by 9: x = 9

The expression simplifies to: -7x-4

44 = 9x +8 36=9x 4=x

It is possible.

-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...

You can solve that equation for either x or y. To solve for y: Subtract 9x from both sides to get -4y=7-9x Divide both sides by -4 to get y=-(7-9x)/4 or -1.75+2.25x

x = -2/3,7/6
