Question

8540-4740:(30икс+49икс)=9480

Answer 1

$8540 - 4740 \div 79x = 9480 \\ - 4740 \div 79x = 9480 - 8540 \\ - 4790 \div 79x = 940 \\ = 940 \times 79 \div 4790$

Answer 2

To solve the equation, let's first combine like terms and then isolate the variable (x).

Step 1: Combine like terms on the left side of the equation: 8540 - 4740 = 3800

Step 2: Rewrite the equation with the combined terms: 3800 = (30x + 49x) + 9480

Step 3: Combine the x terms on the right side of the equation: 3800 = 79x + 9480

Step 4: Isolate the variable (x) on one side of the equation. To do that, we need to get rid of the constant term (9480) on the right side. We can do this by subtracting 9480 from both sides of the equation:

3800 - 9480 = 79x -5680 = 79x

Step 5: Finally, solve for x by dividing both sides by 79:

x = -5680 / 79 x ≈ -71.9

So, the value of x that satisfies the equation is approximately -71.9.
