Answer:

x = 2 and y = -3

Step-by-step explanation:

The given equations are:

2x - 3y = 13 ...(1)

x + 2y = -4 ...(2)

Multiply equation (2) by 2.

2x + 4y = -8 ...(3)

Subtract equation (3) from (1).

2x - 3y-(2x + 4y) = 13-(-8)

2x-3y-2x-4y = 13+8

-7y = 21

y = -3

Put the value of y in equation (2).

x + 2(-3) = -4

x-6=-4

x = 6-4

x = 2

So, the solution of the given equations are x = 2 and y = -3.

What is the solution to the inequality 7<=-3x-4
kipiarov [429]

Answer:

The nearest option is -3 (negative 3)

So, Option B is correct.

Step-by-step explanation:

We need to solve the inequality 7 \leq  -3x-4

Solving:

Step 1: Switching sides of inequality and reversing the inequality

-3x-4\geq 7

Step 2: Adding 4 on both sides

-3x-4+4\geq 7+4\\-3x\geq 11

Step 3: Dividing both sides by -3 and reversing the inequality

\frac{-3x}{-3}\leq \frac{11}{-3}  \\x\leq -3.6\\

The nearest option is -3 (negative 3)

So, Option B is correct.
