Find x when y = 5 in the literal equation 4x + 7y = 51.

x = 4

Step-by-step explanation:

Step 1: Substitute 5 for y and solve

4x + 7 (5) = 51

4x + 35 = 51

Step 2: Subtract 35 from both sides

4x + 35 - 35 = 51 - 35

4x = 16

Step 3: Divide both sides by 4

4x / 4 = 16 / 4

x = 4

Answer: x = 4

x=4

Step-by-step explanation:

4x + 7y = 51

We replace y by 5 and determine x.

4x+7*5=51

4x+35=51

4x=51-35

4x=16

x=4
