Respuesta :
x = 9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
51 = 4x + 15
Step 2: Flip the equation.
4x + 15 = 51
Step 3: Subtract 15 from both sides.
4x + 15 − 15 = 51 − 15
4x = 36
Step 4: Divide both sides by 4.
4x/4 = 36/4
X = 9
Answer:
x= 9
Step-by-step explanation:
C=51
y=3
x=?
Now
C=4x+5y
or, 51=4x+5×3
or, 51= 4x+15
or, 51-15=4x
or, 36=4x
or, 36÷4=x
or, 9=x
Therefore x=9
