Question

Simplify : 2-3

x (– 7)-3

​

Answer 1

10=10

I would begin solving the given equation for x by eliminating the parentheses on the left side by performing the indicated multiplication and then isolating x on one side as follows:

2(x + 2) - 3(x - 3) = x + 7

2x + 4 - 3x + 9 = x + 7

Subtracting x from both sides, we get:

2x + 4 - 3x + 9 - x = x + 7 -x

2x + 4 - 3x + 9 - x = x - x + 7

2x + 4 - 3x + 9 - x = 0 + 7

2x + 4 - 3x + 9 - x = 7

Collecting like terms on the left, we get:

2x - 3x - x + 4 + 9 = 7

(2 - 3 - 1)x + 13 = 7

-2x + 13 = 7

Now, subtracting 13 from both sides, we have:

-2x + 13 - 13 = 7 - 13

-2x + 0 = -6

-2x = -6

Now, dividing both sides by -2:

-2x/-2 = -6/-2

(-2/-2)x = 3

(1)x = 3

x = 3 is the solution to the given equation.

CHECK:

2(x + 2) - 3(x - 3) = x + 7

2(3+ 2) - 3(3 - 3) = 3 + 7

2(5) - 3(0) = 10

10 - 0 = 10

10 = 10
