Respuesta :
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
Answer:
- 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.
