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
9x-5x=4x, 7/4=1.75, x=1.75
The value of x that solves the equation -243 = 90 - 9x is x = -12.
Well, isn't that a happy little math problem we have here? To solve 9 to the power of x equals 243, we can rewrite 243 as 3 to the power of 5. Since 9 is 3 squared, we can rewrite 9 as 3 to the power of 2. Now we have 3 to the power of 2x equals 3 to the power of 5. So, setting the exponents equal to each other, we get 2x equals 5. Therefore, x equals 5 divided by 2, which simplifies to x equals 2.5. Happy solving!
44 = 9x +8 36=9x 4=x
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
x = -3

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
9x-5x=4x, 7/4=1.75, x=1.75
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
