Aset of equations is given below:

equation a: c = 2d + 1
equation b: c = 3d + 5

which of the following is a step that can be used to find the solution to the set of equations?

2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1

The correct option is 1.

Step-by-step explanation:

The given set of equations is

Equation A: c = 2d + 1

Equation B: c = 3d + 5

Using equation A and equation B, equate the value of c.

The value of d is -4. So the value of c is

The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

10

step-by-step explanation:

7+3=10
