Answer:
x = 7 and x = 5
Step-by-step explanation:
12x - 35 = x²
x² - 12x + 35 = 0
(x - 7)(x - 5) = 0
x = 7 and x = 5
The least common denominator is 15.
Distribute on the left
2x-2+3x=3
Combine like terms
5x-2=3
Add 2 to both sides
5x=5
Divide both sides by 5
x=1
Final answer: x=1
Solution:
1) Solve for x in 3x+7y=-1
x=\frac{-1-7y}{3}
2) Substitute x=\frac{-1-7y}{3} into 4x-3y=11
\frac{4(-1-7y)}{3}-3y=11
3) Solve for y in \frac{4(-1-7y)}{3}-3y=11
y=-1
4) Substitute y=-1 into x=\frac{-1-7y}{3}
x=2
5) Therefore,
x=2
y=-1
Done!
