14 = 31.7 - 3x
-17.7 = -3x <---- I subtracted 31.7 from both sides
5.9 = x <---- I divided both sides by -3
I think it is .8 i could be wrong i’m not sure
-25 - 12x = -(-8x - 6) - 3(5x + 12)
Distributive property.
-25 - 12x = 8x + 6 - 15x - 36
Combine like terms.
-25 - 12x = -7x - 30
Add 12x to both sides.
-25 = 5x - 30
Add 30 to both sides.
5 = 5x
Divide both sides by 5.
x = 1
The x-intersect is 1.
14-5+20÷2∧2+4
exponent first: 14-5+20÷4+4
Divide: 14-5+5+4
Solve left to right: 9+5+4
add all: 14+4 = 18
