Answer:
x=4
Step-by-step explanation:
-3(4x+3)+4(6x+1)=43
distribute the -3 and 4
-12x-9+24x+4=43
combine like terms
12x-5=43
add 5 on both sides
12x=48
divide 12 on both sides
x=4
Answer: 5/9
Solution: 2x^2+16x-10=0
According to formula: X=(-16+_sqrt(16^2-(-10•2)) / 2•2
X=5/9
Answer:
y <7
Step-by-step explanation:
15-y>8
Subtract 15 from each side
15-15-y>8-15
-y>-7
Multiply each side by -1, remembering to flip the inequality
-1 * -y > -7*-7
y <7
Solutions: x=3 , y=5 , z=2
x+y+z=10
2x-5y+2z=-15
4x+y-z=15
Answer:
n = 2
Step-by-step explanation:
2 - 22 = -9n + 22 - n - 22
-20 = -9n - n
-20 = -10n
-20/-10 = -10/-10n
-2 = -n
n = 2
