Substitution y=2x-1 Y=-3x-6

Mathematics

Y = 2x - 1
y = -3x - 6

Since y of the first equation is equal to y of the second equation, then what each y is equal to in the two equations is equal.

2x - 1 = -3x - 6

Add 3x to both sides.

5x - 1 = -6

Add 1 to both sides.

5x = -5

Divide both sides by 5.

x = -1

Now substitute -1 for x in the first original equation.

y = 2x - 1

y = 2(-1) - 1

y = -2 - 1

y = -3

Solution: x = -1 and y = -3

What is the probability that 1 or 2 are rolled on a number cube with sides numbered 1, 2, 3, 4,
choli [55]

Answer: \frac{1}{3}

Step-by-step explanation:

total sides = 6

p (rolling a 1) = \frac{1}{6}

p (rolling a 2) = \frac{1}{6\\}

Note:

or - add

and - multiply

∴ \frac{1}{6} +\frac{1}{6} = \frac{2}{6}

∴ \frac{2}{6} = \frac{1}{3}

hence, p (rolling a 1 or 2) = \frac{1}{3}
