leva [86]

ANSWER

B. (-2,-3)

EXPLANATION

The given equation is

$7x - 5y = 1$

We want determine which of the ordered pairs is a solution to the given equation.

For point A(-3,-2)

$7( - 3) - 5( - 2) = 1$

$- 21 + 7 = 1$

This statement is false.

For option B(-2,-3)

We have

$7( - 2) - 5( - 3) = 1$

$- 14 + 15 = 1$

For option C(0,4)

We have

$7(0) - 5(4)=1$

$0 - 20=1$

For option D(4,0)

We have

$7(4) - 5(0)=1$

$28 - 0=1$

This statement is false.

2x+5+2x+3x=6x+7<br> Help ASAP plzzzzz

BartSMP [9]

Answer: X=2

2x plus 2x plus 3x equals 7x and then you add the +5 which means you now have 7x+5=6x+7 which you then solve from there by subtracting the 6x from the left side. You then get x+5=7 meaning x=2.
