Solve each of these systems using the substitution method. make sure to check your answers ! 2x + 3y = -4 x − 2y = 5 a. x = 1, y = -2 b. x = -1, y = 2 c. x = 1, y = 2 d. x = -2, y = -1

a. x = 1, y = -2

Step-by-step explanation:

The given equations are 2x + 3y = -4 (1)

x - 2y = 5 (2)

From the second equation, we get x = 2y + 5

Now plug in x = 2y + 5 in the first equation, we get

2(2y + 5) + 3y = - 4

4y + 10 + 3y = -4

7y + 10 = -4

7y = -14

y = -2

Now plug in y = -2 in x = 2y + 5 to find the x value.

x = 2(-2) + 5

x = -4 + 5

x = 1

Therefore, x = 1, y = -2

Thank you.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
