what is the value of x in the equation $8x - 2y = 48$, when $y = 4$?\n○ 6\n○ 7\n○ 14\n○ 48
Answer
Explanation:
Step1: Substitute y = 4 into the equation
We have the equation (8x - 2y = 48). Substitute (y = 4) into it, so we get (8x - 2\times4 = 48).
Step2: Simplify the equation
Calculate (2\times4 = 8), then the equation becomes (8x - 8 = 48). Add 8 to both sides of the equation: (8x - 8 + 8 = 48 + 8), which simplifies to (8x = 56).
Step3: Solve for x
Divide both sides of the equation (8x = 56) by 8: (x=\frac{56}{8}=7).
