Answer 1

To isolate the variable term on one side of the equation, subtract 7x from both sides and simplify the expression. Then subtract 18 from both sides and divide by -10 to find the value of x.

Step-by-step explanation:

To isolate the variable term to one side of the equation -3x + 18 = 7x, you need to perform the same operation on both sides of the equation. In this case, you can either add 3x to both sides or subtract 7x from both sides.

Let's subtract 7x from both sides: -3x + 18 - 7x = 0

Combining like terms: -10x + 18 = 0

Finally, subtract 18 from both sides: -10x = -18

Dividing both sides by -10: x = 1.8
