Find the equation with solution x=5x=5. Possible equations: 8x+1=418x+1=41 5x+7=355x+7=35 9x4=419x-4=-41 4x+1=614x+1=61

STEP 1

Assumptions
1. We are looking for the equation that has the solution x=5x=5.
2. The options given are: a. 8x+1=418x + 1 = 41 b. 5x+7=355x + 7 = 35 c. 9x4=419x - 4 = -41 d. 4x+1=614x + 1 = 61

STEP 2

We will substitute x=5x=5 into each of the equations to check which one is true.

STEP 3

Substitute x=5x=5 into the first equation.
8x+1=418x + 1 = 41
8(5)+1=418(5) + 1 = 41

STEP 4

Calculate the left side of the equation after substitution.
8(5)+1=40+1=418(5) + 1 = 40 + 1 = 41

STEP 5

Since the left side equals the right side after the substitution, the first equation is true for x=5x=5.

STEP 6

For completeness, let's check the other options as well.

STEP 7

Substitute x=5x=5 into the second equation.
5x+7=355x + 7 = 35
5(5)+7=355(5) + 7 = 35

STEP 8

Calculate the left side of the equation after substitution.
5(5)+7=25+7=325(5) + 7 = 25 + 7 = 32

STEP 9

Since the left side does not equal the right side, the second equation is not true for x=5x=5.

STEP 10

Substitute x=5x=5 into the third equation.
9x4=419x - 4 = -41
9(5)4=419(5) - 4 = -41

STEP 11

Calculate the left side of the equation after substitution.
9(5)4=454=419(5) - 4 = 45 - 4 = 41

STEP 12

Since the left side does not equal the right side, the third equation is not true for x=5x=5.

STEP 13

Substitute x=5x=5 into the fourth equation.
4x+1=614x + 1 = 61
4(5)+1=614(5) + 1 = 61

STEP 14

Calculate the left side of the equation after substitution.
4(5)+1=20+1=214(5) + 1 = 20 + 1 = 21

STEP 15

Since the left side does not equal the right side, the fourth equation is not true for x=5x=5.

STEP 16

After checking all options, we have found that the equation 8x+1=418x + 1 = 41 is the only one that holds true for x=5x=5.
The equation with the solution x=5x=5 is 8x+1=418x + 1 = 41.
