First, you have to distribute the -1 throughout the parentheses, which gives you 7x-3x-10=-46.
Then, you combine 7x and -3x, which gives you 4x-10=-46.
Then, you add 10 to both sides of the equation, which gives you 4x=-36.
FInally, you divide both sides of the equation by 4, which gives you x=-9.

Answer:
x = ±√(c/a)
Step-by-step explanation:
Undo what is done to x.
ax² -c = 0
ax² = c . . . . . . add c
x² = c/a . . . . . . divide by a
x = ±√(c/a) . . . . take the square root
djdusijsjsiwidjjdjdjsjd is equal to djdusijsjsiwidjjdjdjsjd
How to solve?: First you will get you alike terms on the same side. You will do this by subtracting 5 on both sides of your sign and will therefore get the equation to where -5 and -3 is on the same side and looks like -5 - 3. Then you will combine your -5 and -3 and get -8. Now you will take your -2x and divide both sides by -2 to where your able to get your variable x alone. You will then get -8 divided by -2 and your answer would be -4.
Answer: -4
