Is (2, -3) a solution of x + 5y = 4?

givi [52]

So for this, plug in 2 into the x variable and -3 into the y variable and solve.

$2+5(-3)=4\\ 2+(-15)=4\\ -13=4$

Since -13 = 4 is a false statement, (2,-3) is not a solution to this equation.

Evaluate 2-10+8-\left(-2\right)2−10+8−(−2)2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis.

dedylja [7]

Answer:

Here we want to solve the equation:

"2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis."

This can be written as:

2 - 10 + 8 - (-2)

Remember that we can solve this in any order we want, so let's go from left to right:

So we can solve first:

( 2 - 10) + 8 - (-2)

We know that:

2 - 10 = -8

Then we can replace that in the expression to get:

( 2 - 10) + 8 - (-2) = -8 + 8 -(-2)

Now we can solve:

(-8 + 8) - (-2)

We know that:

-8 + 8 = 0

Replacing that in the equation we get:

(-8 + 8) - (-2) = 0 - (-2) = -(-2)

And now we can remember the rule of the signs:

(+)*(+) = (+)

(-)*(-) = (+)

(-)*(+) = (-)

(+)*(-) = (-)

Then:

-(-2) = (-1)*(-2) = +(1)*(2) = 2

The solution of the expression is 2.
