Question

Solve for x in the equation 2x+3y=78 when y=5

Answer 1

• x = 31.5

Step-by-step Solution:

• 2x + 3y = 78

Substituting the value of y.

• => 2x + 3(5) = 78

Solving:

• => 2x + 15 = 78
• => 2x = 78 - 15

Dividing:

• => 2x = 63
• => x = 63/2
• => x = 31.5

Hence, the value of x is 31.5.

Answer 2

Putting the value of y=5 in 2x+3y=78

2x+3×5=78

2x+15=78

2x=78-15

2x=63

x=31.5

Therefore,the value of x is 31.5
