Question

4a) mg=7x-15, fg=33, x=?

Explanation:

Step1: Assume MG = FG (since no other info, equate for solution)

$7x - 15 = 33$

Step2: Add 15 to both sides

$7x - 15 + 15 = 33 + 15$
$7x = 48$ (Wait, correction: 33 + 15 = 48? No, 33 + 15 is 48? Wait, 33 + 15 = 48? Wait, 33 + 15: 30 + 15 = 45, 3 + 0 = 3, so 48? Wait, no, 33 + 15: 33 + 10 = 43, 43 + 5 = 48. Yes. Then divide by 7? Wait, no, maybe I misassumed. Wait, maybe MG = FG? Wait, maybe the problem is that MG and FG are equal? Let's recheck. If MG = 7x -15 and FG = 33, and if MG = FG, then:

Step1: Set MG = FG

$7x - 15 = 33$

Step2: Add 15 to both sides

$7x = 33 + 15$
$7x = 48$ (Wait, 33 + 15 is 48? Wait, 33 + 15: 33 + 10 = 43, 43 + 5 = 48. Yes. Then x = 48/7? But that's a fraction. Wait, maybe I made a mistake. Wait, maybe the problem is MG = FG, but maybe the numbers are different? Wait, maybe the original problem has MG = FG, but maybe I misread. Wait, let's check again. The problem is 4a) MG = 7x -15, FG = 33, x =? So assuming MG = FG, then:

$7x - 15 = 33$
Add 15 to both sides: $7x = 33 + 15 = 48$
Then x = 48/7 ≈ 6.857. But that seems odd. Wait, maybe the problem is MG = FG, but maybe the numbers are different? Wait, maybe it's a typo, or maybe I misread. Wait, maybe FG is equal to MG, so solving 7x -15 = 33. Let's do that again.

Step1: Start with equation

$7x - 15 = 33$

Step2: Add 15 to both sides

$7x = 33 + 15$
$7x = 48$

Step3: Divide both sides by 7

$x = \frac{48}{7}$ or approximately 6.86. But maybe the problem was supposed to be MG = FG, and maybe the numbers are different? Wait, maybe I misread FG as 33, but maybe it's 35? No, the user wrote 33. Alternatively, maybe MG is equal to FG, so the solution is x = 48/7. But let's proceed.

Answer:

$\frac{48}{7}$ (or approximately 6.86)
