Answer:
3
Step-by-step explanation:
The whole goal is to isolate the variable.
3x-1=8
1+3x-1=8+1 first add 1 to both sides of the equation to cancel out the -1
3x=9 now just divide 3 to both sides of the equation because the opposite of multiplication is division. So dividing 3 on both sides cancels out the 3 to isolate the x
3x/3=9/3
x=3
Answer:
3
Step-by-step explanation:
42 divided by 14 is equal to 3
42/14=3
<span>-3 = x^2 + 4x + 1
Add 3 to both sides.
0 = x^2 + 4x + 4
Switch sides.
x^2 + 4x + 4 = 0
For the quadratic formula, a = 1, b = 4, c = 4
discriminant = b^2 - 4ac = 4^2 - 4(1)(4) = 16 - 16 = 0
When the discriminant equals zero, there is a single real solution.
Answer: There is a single, real solution.</span>
